CHAMP'S TESTIMONIALS

 

 

Ethan, one of John's clients, with his Impact Amp Head after receiving it back after repair by Champ Electronics.

 

Probably the biggest "Buzz" that I get from repairing and modifying vintage amps is from the pleasure and satisfaction that owners display when I re-unite them with their amps after I have finished working on them. Many of them are kind enough to write to me after they have had chance to use the equipment back in their own homes or on stage, and provide me with their impressions of my work. I am naturally very proud to receive such testimonials, some recent ones of which I display below.

 

From Harmonica Player Richard - 1959 Tweed Fender Champ - April 2008

"John. Great to see you yesterday with my Fender Champ 59.  Thanks for your attention and suggestions as they have made a world of difference. I took it home and first fitted the Russian Military 6V6 you supplied and that made a noticeable difference to the tone. Equally impressive was the Russian Military 5U4M rectifier – more power and even better tone again. I swapped out the pre-amp valve for a Mazda ECC82 which I had and now I have plenty of headroom without the early feedback. Next I fitted the early 60’s, 4 ohm Celestion 8" speaker you kindly lent me to try – much better than the re-conned original which, incidentally, had a piece of felt cut out by a "blind person!", stuck in the middle for a dust-cap! Quality rubbish job then!

It was great to meet someone who is straight and direct about valves and valve amps, as there is too much old-wive's-tales and smoke and mirrors! Plus it was an education to see the amp being tested and the effect of different valves actually demonstrated on your test equipment.

Many thanks and I will call you in a few weeks to sort out my Fender 62. 

Best Regards, Richard."




From Ken - Dallas Scala Baby Five Watt Combo - April 2008
 
"Hi John. Just a short note to let you know that the amp works and sounds fine. The buzz that you mentioned is still there a little, but I have to turn the tone and volume right up to max to get it. At this volume the amp shakes the windows; not really the effect I was looking for at all! Lowering the volume gets me a nice tone with the slide guitar. Thanks for bringing my little amp back to life, sounds better than it ever did.

All the Best, Ken."



From Russ - Hiwatt Custom 100 DR103 - April 2008
 
"Hi John. Just thought I'd let you know how the Hiwatt is doing. Since you found the broken bit in the valve socket, reliability has been returned, and the new pre-amp valves you fitted mean that my bass through it sounds frankly.......awesome! Pity the guitarist....! Thanks for a friendly, profesional & quick job.

Russ & A Happy Hiwatt DR103."



From Billy - Sixties Vox AC30 + The Making/Fitting Of A Top Boost Mod - April 2008
 
"Hi John. I thought I'd email you to say thanks for doing such a great job on my AC30. I played it all day yesterday (burning the chips, I was cooking in the process, whoops!) and I have to say it absolutely ROCKS!! I was also able to open it up properly last night as I was in the studio and I was blown away! It sounded bloody gorgeous, I thought it sounded nice before I brought it to you but now it really sings.

It sounds much warmer then my Korg reissue and there's a lot less noticeable hiss from my old AC30 compared with my modern one. I was able to have the brilliant volume on full tilt without hardly any hiss at all, I definitely wouldn't be able to do this on my modern Korg reissue. I'm glad I went with the Vib/Trem pedal being fitted as well, the Tremolo sounds great, real vintage vibe, love it.

So thanks you for all the hard work you put into restoring my amp to its former glories, I can't wait to get it on stage for my next gig which is where these amps belong in my opinion. Also thanks for being so welcoming and for all the advice... and tea! It was a real treat to get to see you at work too. I'll no doubt be back to see you again sometime in the future with my old Orange amp that could do with your magic touch. Cheers John.

Yours sincerely, Billy."




From Ged - Fender Vibro Champ - March 2008

"Hello John. The Vibrochamp really does sound good now, all buzzes and crackles have been banished, and it's sitting happily on top my Cornford Harly. A combined 12 watts that sounds really good courtesy of a Roger Mayer Crossroads AB box to avoid earth hum. I'm dead happy. I'm still using my old leads, so I'm sure the problem must have been down to the loose strand of wire you mentioned in your email. Anyway, thanks again.

All the best,Ged."



From Chris - Proamplifiers VSQ65 - March 2008
 
"Hi John. I finally got the opportunity to plug her in yesterday evening and was quite literally blown away! I thought I would try things easy to start with so set the master volume at about 4 with the gain full up. F**k me John, you have created an ANIMAL!;-) I simply can't get the volume past 4 for fear of structural damage and a possible lynching from the neighbours! My face was acheing from grinning! I never thought for a second that the amp that had caused me so much heartache, and you so much headache could sound so good! A thousand thank you's.

I have since re-called our experiences to a bass playing friend who has a 100watt Hiwatt or Ampeg bass head (I can't remember which) He will contact you soon for some of your "magic" too.

I got a small refund from the guy who sold the amp to me on EBay, thanks for your help in that. A bit more would have been nice but to be honest; after hearing the amp, I really couldn't care now;-) The amp's a keeper for sure! Look after your self and keep doing what you do best!

Best regards, Chris."



From Oliver in France - Echolette M120 PA Head - March 2008

"Hi John. The Echolette sounds very good and quite loud too....I'm happy to report. Thank you for your great work.

Cheers, Oliver"



F
rom Ste - 1963 Vox AC30 Head - March 2008
 
"Hi John. It was good to finally meet you yesterday and be re-united with my rejuvenated AC30. We had a good journey home and I tried the amp as soon as I got in. I am extremely pleased with the results of your labours, but had forgotten how loud these amps can be! Hope the neighbours are understanding and enjoy rock music!
 
Thanks again. Will be in touch in the near future with some of my various amp rescues.
 
All the best, Ste."




From Damian - Fender Tweed Bassman and a Telefunken valve 1960's mic pre-amp - February 2008

"Dear John. Thank you so much for the excellent work you did on my Tweed Bassman amp, it sounds completely revived...it has had the kiss of life and is now like a Bassman on steroids!! Its a real comfort to meet someone who goes the extra mile.....

My Telefunken V76 mic pre-amp is also well happy to have met you too!

Cheers Guv', Damian."


From Rod in Margate who apparently has just missed Sunday Lunch!  - February 2008

"Hi John. I have just accidently stumbled upon your website (well actually about 4 hours ago!) and I have been totally engrossed with it, and cannot seem to tear myself away from the computer!! I have even got into serious trouble with the other-half over missing my Sunday lunch (that's a 1st for me!). Let me just say what a great site you have and what a bottomless font of knowledge you appear to be!! If I ever have trouble with my current amp (1982 Fender Concert 4x10 - Paul Rivera designed) I know where to come; and yes, Paul Rivera did work for Fender in the early 80's, apparently to bring back some of the sales that Fender amps apparently lost by bad design/reliability problems in the mid to late 70's....Once again, thanks for the totally engrossing site!!

Regards, Rod (Margate, UK)"


From Peter in Barbados (Yes, Really!!)- 1962 Vox AC30 Head - February 2008

"Got it back, lovely, thanks John. Its just great...never had it without a hummmm before, didn't know it was possible! The tremolo is nice, but do you know what is nicer, playing that mellow main channel quietly. Now this maybe because I am older than dirt but what a lovely full sound!

A good thrash this evening beckons. Thanks for your knowledgeable work, such a relief to find a competent craftsman who works to a fine level. My amp was lucky.
Thank God I didn't give it to someone local!

Best regards, Peter."


From Andy - Sound City 50 & Peavey 5150 Combo - January 2008

"Hi John. Tried both amps briefly last night. I honestly struggled to keep the Peavey at an acceptable level! As for the Sound City - what a difference! It's now about twice the volume on the low gain setting than it was on the high gain setting before you worked your magic on it. Can't wait to try them in anger! Will keep you posted.

Will recommend you to every amp owner I know!
 
Cheers for now, Andy."


And again from Andy a few days later!
 
"Hi John.

Took both amps to rehearsal tonight; tried the Sound City first through the Peavey's speakers (the cable will just reach). Absolutely awesome! Proper vintage valve overdrive; for a minute I thought I was Pete Townsend (I believe Sound City were early versions of Hiwatt amps?) I had an overdrive pre-amp pedal on the floor for solos and when I kicked this in I then thought I was Hendrix!, but believe me this was all to do with the amp as opposed to any voodoo guitar skills! I play a Strat almost always and was surprised at how fat and rich it sounded (after much tweaking of those active controls on the Sound City) and how the single coils pushed it into that sweet overdrive even at just over half volume. I can't believe the transformation in this little amp that I've owned for so long but have rarely used because it was so duff!! Almost reluctantly, I switched to the Peavey (my main amp for the last few years). I was considering selling this amp just before it packed up and buying a Marshall but after tonight, no way! It's definitely louder than it was before but more importantly the tone is greatly improved with a much tighter rhythm sound and less 'mushy' with single string work being much smoother and creamier than before. Only problem now is that the wife wants me to sell one or the other and they are now both so great but both so different. The Peavey is more versatile with it's modern layout but the Sound City is just so wonderful with it's proper (not modelled) vintage tone and feel. Perhaps if I get her some flowers she'll let me keep both?

Many thanks John for your wonderful work. You are a true craftsman and there ain't many left! Long may you continue your mystical amp voodoo.

Andy."


From Jon - Marshall TSL 100 - January 2008

"Hi John. I finally got around to mailing you about the re-valving you did on my Marshall TSL100.  In short, it sounds great!  I was explaining to you about how I needed to compete with my other guitarist's SG, and I certainly do now!  It's hard for me to tell the difference that the new valves have made without being able to compare directly, but the one thing I can definitely say is that it sounds AWESOME!!

Cheers! Jon."

 
Footnote to this mail:- What Jon means in his statement "It's hard for me to tell the difference that the new valves have made without being able to compare directly" is that his quad of EL34's were kaput and needed to be replaced. However, when anybody brings me a 100 watt head of any kind, and especially for guitar use (rather than bass guitar), utilizing a quad of EL34's, I always advise a combination of 2 x JJ EL34's and 2 x JJ KT77's. The combination of the 2 pairs adds something to the sound of the amps and is always very pleasing!!
 
This is because the EL34 is a pentode and the KT77 is a beam tetrode.....the combination of the two gives great results, but one does have to know how to bias the combination pairs correctly! John.

From Simon - Sound City Bass Concord Combo - January 2008

"Hi John!  Managed to do some recording with my band last weekend and used the Sound City Bass Concord.  Very, very pleased with the sound. Prefer it to my Sound City 120 / Ampeg rig!, though that needs a service too.  The Fanes are nice, tight and punchy; just what I was after. Need to get the back panel sorted for it as it was a little lacking in low end!

Thanks again for the good work. One day I might ask you to sort out the Sound City 120 head but as I'm using the Concord now there's no immediate hurry.
 
All the best, Simon."


From Graham - Vox AC4 & a Champ Treboost+ (My own clone of the Dallas Arbiter/Rangemaster Treble Booster + Extras!) - December 2007

"Hi John. The amp is now a delight - it now has surprising clarity and sparkle with hardly a hint of its earlier muddiness - whatever you did with that tiny mod has improved it no end - not so much a treble thing but more of what would be termed the "Presence" or "Brightness" of a bigger amp!
 
I have spent hours with it today and it really has become a nice little thing - a very tactile and responsive feel; quite the opposite of what you normally get from these things - very pleasantly surprised!! Also the trem set-up - normally the trem on these smaller British (and American) amps is relatively unusable or at best something you would only find a use for occasionally but by getting that little trim pot installed it has all changed - with some reverb added into the mix it now has what is practically a "chorus" sound as opposed to what I would normally think of as a tremolo - very nice indeed and now a very usable effect - I am very pleased!!
 
Your "own designed" treble boost arrived this afternoon - I opened her up and was impressed by the innards - very tidy, not as if I expected anything else from you! I set it up through the Vox AC4 and tried it out against several other treble boosters I had kicking around - basically I did some side by side comparisons with an original Rangemaster by Dallas - and a rare treble/bass booster face by Arbiter (both from the days before they amalgamated into the better known Dallas-Arbiter of fuzz face fame) and what is considered by many to be one of the best current RM clones the Analogman Beano Boost - Your box of tricks holds up very well indeed - the only major difference is it lacks the overall gain (volume boost) of the original although it is very similar in its sound giving a great clarity - particularly noticeable when using chords - it lets all the notes get heard and giving a very nice bit of overdrive when playing lead - I couldn't help myself but started hitting some Rock & Roll riffs on a Fender (you know Johnny B' Goode and all that stuff) - it thickened up the sound very nicely indeed and although I only used it on the small Vox it was bloody good at tilting that EL84 over into a nicely sustained overdriven sound. I found (so far ) that I just left the Gain control maxed and used either the second or third tone filter setting. Apart from on the most bass of the four settings I felt that my speaker was safe (you know how hard it is to get these old 4 ohm jobs!) I certainly didn't want to have to own up to "breaking" the amp less than a day after getting it back..
 
Your design Treboost+ pedal sits exactly with it's middle two tone settings as good as any of the others I tried, so I think it will prove to be a very useable bit of kit; particularly when you think that it only runs to about a tenth of the cost of replacing the original Dallas-Arbiter Treble Booster!!
 
Kind Regards & Many Thanks indeed - Graham."


From Chris - Linear Concord 30 - December 2007

"Dear John. Thanks for re-building my Linear Concord. It sounds surprisingly good!
 
Best regards, Chris."

From Ed - Wem Dominator Mk III - December 2007

"Hi John. They are in and glowing, sounds really nice. If I were a techie I would say that the amp has a lovely warm tone but as I'm not; I'll say it sounds nice!
 
Many regards, Ed."

From Jim - Impact 60 Head - December 2007

"Hi John. Tried the amp last night, very nice. Quite a wide ranging tone, warm and mellow when the bass is raised (especially with the SG set to neck humbucker). Thanks for a good job well done!
 
Jim."

From Pete - Rivera Quiana 112 Combo - November 2007

"Hi John, it's Pete. I brought over the Rivera Quiana 112 amp last week. I've used it at two gigs and with no probs at all, so it looks like you cured the fault for me! Thanks very much for your time.

Pete"

From Tim - Gem Venus and a Selmer T n' B Mk I - November 2007

"Hi JohnJust a quick note to say how pleased I am with both amps. The Selmer is sooooo loud! Its far louder and quieter (hum/hiss etc) than any Selmer I've ever encountered and its great to find someone who could bring the old gal back to life. I'm sure it will be on a stage with me very soon! If only all Selmers were this good!
 
The Venus is a revalation. I still can't believe how good this thing sounds. It's so hum-free, yet so warm and crystal clear. I've owned and recorded with quite a few amps over the years and this is up in the top five of all time. I've recorded some Gilmour-Esque stuff with it and it excells with a couple of pedals in front of it. I am over the moon with this amp and reckon it to be one of the biggest bargains of my life thus far. No doubt it will be my first choice for recording from now on...
 
Once again, thanks mate. Speak soon. Tim."

From Chris - Selmer T&B Mk III and a Carlsbro CS60 PA Head - November 2007

"Hi John.........I can report that FIRST: the Selmer Mk3 is sounding better than ever with your earthing "tidy up" and new ECC83's. Man, I love the sound of that amp!!! However, on the guitar side, the Carlsbro is EVEN BETTER THAN THE SELMER!!! The bass doesn't quite do it just yet, but there's not much in it.......it's just a bit less warm or something. Anyway, thanks again for a great service.

Chris."
 

From Steve - Peavey Classic 30 Combo - November 2007

"John. Thanks for your help. amp working & sounding better than ever! Keep on rockin'

Cheers, Steve"


From Andi - Marshall 50 Mk II Lead Combo - October 2007

"Hi John. Sorry I haven't replied. Just to say though, that I am well-chuffed with the amp. The clarity of the sound is much better and brighter than before and the overdrive seems to be more consistent. Whatever the problem was it now seems to be fixed and I spend large parts of the weekend getting sore fingers. Many thanks for all of your help & hope to see you again (although not too soon of course!)
 
Cheers, Andi"

From Andi again in January 2008, regarding the same amp.

Hi John. Just wanted to let you know that I am still dead chuffed with the work you
did on my amp - it is sounding 'sweet as' and I can't thank you enough.
 
Cheers! Andi.

From Richard - Laney LC15 Combo - October 2007

"Hi John. Thanks for the photos and for the work done.  The amp sounds great and the new output transformer has really improved the tone, headroom and power-stage overdrive.

Cheers, Richard"


From Jean-Paul - Selmer Zodiac 30 (Power Amp only) - October 2007

"Hi John. Just wanted to let you know the amp is working great!  I plugged it in last night and was delighted.  Today I am going to crank it up (as it was late last night) and enjoy it for the first time in ages!  Thanks for your hard work.

Kind regards, Jean-Paul"


From Eric - Sound City 200 PA Head - October 2007

"Hi John. Just sending an e-mail to say thanks, the amp sounds great! See you soon about my other amp.

Cheers, Eric."


From Rob - Two Fender "75" amps - October 2007

"Hi John. Both Fender 75's sound fantastic now. Thanks so much.

All the best, Rob"


From Steve - Stentor Combo - October 2007

Hi John. As expected the Stentor sounds superb even to my ears....If I had to describe the sound it would be warm and rich sounding, and it breaks up nicely around 2/3 volume! I should be taking both amps to my friend Paul next week so he can try them both out, as he is eager to hear them as he knows your reputation.
Catch you later, Steve."

From Alec - Orange AD30R - September 2007

"Hey John. Played a gig with the Orange a couple nights ago and its sounding gorgeous, really beautiful. Thank you for your work on her, your patience is very much appreciated.

Alec."



From Edward & Sharon - Leak and Varislope HiFi - September 2007

"Having inherited a Leak Stereo 20 Power Amplifier and Varislope Pre-Amplifier, and having been used to listening to its sweet sound in the past, I was aware that it needed some attention.  I contacted John Chambers who agreed to overhaul both units.  I left them with him, trusting in his abilities.  I could not have chosen better.  Both the beauty of his work and the beauty of the sound could not fail to please any audiophile.  In short, anybody who finds themselves in the same situation need look no further.  I have no hesitation in recommending John’s thoroughness and skill.

Edward & Sharon, Norfolk, UK."

From Clive - Relyon HiFi Amp - September 2007

"John. Thanks again for a great afternoon and for getting the little Relyon hi-fi amp up and running..........buzz free! Look forward to seeing you again perhaps later in the year. (I'll bring that old A60 if that's OK?)

Best regards, Clive."


From Mike - Selmer Bassmaster 50 - August 2007

"Hi John. Many thanks for the photo's.  I used the amp last night and it worked fine.  No drop off in volume, and the tone was great.
Many thanks for your work, it's much appreciated.

Regards Mike"


 

From Steve - Sound City Concord and B & M Crown - August 2007

"Hi John. I had a quick go with the Sound City Concord and even with my bad playing and practically deaf hearing I can honestly say this....there is no hum whatsoever and I have to have the volume 3/4 full as I cannot hardly hear! On chords, you can hear every note...it's very clean and crystal like...imagine hitting a bell, that's what it sounds like...you hear every note. I thought my "Oliver G150R" was clean, but no where near as clear as this; it just chimes...! I played a few bars of "House Of The Rising Sun" and it sounded superb....really chuffed, thank you. I cannot wait to hear my friend play through it...I only wish my hearing was better as I have to have everything on high volume which sounds normal to me...!

Onto the B & M Crown. Being only 5 watts, I have to crank it up to hear it and then it distorts (lol) but it clips nicely....I'll have to get my ears sorted!! I will ask my friend to e-mail you directly without any influence from me to give you his honest opinion!

Cheers for now mate and nice to have seen you again also. Many, many thanks indeed for a great service.  Steve"

 

From Anthony - Fender Twin - July 2007

"John. Delighted to say we had a great gig, everything on the Twin functioned perfectly which made a nice change. We got 3 encores and a repeat booking in 4 weeks.

Thanks once again for sorting it out. Ant."

 

From Matt - Fender Twin-Amp - July 2007

"Hi John. Thanks for the photos. The amp sounds absolutely incredible, the tones when the distortion kicks in are amazing. We had a great rehearsal tonight, my amp has never sounded so good.

Thanks for all your hard work. Matt"

AND...........

"Hi John. I’m more than happy for you to put my email on the testimonial page. Thanks again – our bass player was still going on about how good my amp sounded this morning!! Matt"

 

From Neil - Fender Twin Amp - July 2007

"Hi John. Many thanks for your enthusiasm and care in the repair of my Fender Twin amp. Your attention to detail is second to none and I would recommend you without hesitation to all tube amp guitarists like me, who have struggled to find someone with the knowledge and skill to repair and service their amp properly. I think my "Twin" sounds as good now as the day I bought it!

Many thanks, Neil - Chesterfield."


From Robin - Linear Diatonic Amp - July 2007

"Hi John. Just a quick note to thank you for the speedy and efficient repair of my Linear Diatonic amp which has been languishing for some months waiting for someone who knew what they were doing! I tried it when I got home and it is sounding fine.

Robin"

 

From John - Dulci Amp - June 2007

"Hi John. Sorry for taking a while to get back to you. It was great meeting you and seeing your workshop. The Dulci amp works great. Thank you.

John (Leicester)"


From Justin - Vox AC 30 - June 2007

"Hi John. I used the Vox AC30 at the weekend to good effect, plus it was on hire on Wednesday - everyone that tries it is impressed...!

All the best, Justin"

 

From Paul - Triumph Leo - June 2007

"Hi John. I received my little Leo amp today, and just like a kid at Christmas I tore open the packaging and plugged her straight in! Well, what can I say!? What a transformation! All the nasty hiss has completely vanished, and the hum is barely noticeable, plus it is so much LOUDER!!!! than it was (I can't believe it's only a 4 or 5 watt amp!). I can only describe the sound as "Sumptuous" and the tremolo (or should that be Vibrato?) is perfect. So I can only say Thank You!, not only for the excellent job that you did on it, but also for going that extra mile with the addition of some really great little modifications, which has given me far greater control over the sound. (This little amp was definitely in the right hands!).

I will be in touch soon!.... : ) All the best. Paul"

 

From Cliff - Five Amps....Bird Golden Eagle; Bird Talisman; Sound City Concord; Shaftsbury Scala; Small Fender Combo - May 2007

"Hi John. I had a good journey back to Preston, (less than two hours) and, after a quick bite to eat, I thought I'd have a play with my Bird (!!) - The Golden Eagle. What can I say - it's absolutely fantastic, (it was really good before but I was always slightly distracted by the hum). Now the hum has gone it's just perfect. I connected it up to an extension speaker for the first time and I 've been grinning like a kid ever since! By the way - thanks for the tip about making sure the extension cab was correctly wired - mine wasn't, but I would never have known about the "battery phasing check" if you hadn't shown me. I'll give the other amps a workout over the next few days and let you know how I get on, although I've no doubt they will all be great! Thanks for your hospitality and great service. If I may, I'll book in my other amps for a service with you in a few months, (Wem Clubman, 2 little Silvertones and the Carlsbro TC60).

Cheers for now and kind regards. Cliff."

 

From Dieter in Germany - Geloso Amp - May 2007

"Hello John. By now I got my Geloso G1.1070 working very nice on a pair of EL36, and all thanks to your works I now have a perfectly functioning and lovely sounding valve amplifier at a total cost of about €100!

Kind regards, Dieter."

 

From Josh - Marshall VBA400 - April 2007

"Hi John. The amp is now amazing mate. This Marshall VBA-400 is fantastic now!! It's bloody brilliant!! I got the cab for it and everything is working perfectly, it sounds amazing, even when turned up enough so that the pictures vibrate off the walls! Thanks again for the repair and for a really good price. Hope you and your workshop are doing well! 

Josh."

 

From David - Vox AC30 Output Transformer Re-Wind - April 2007

"Hi John. The transformer arrived this morning and within half an hour it was in and singing fine. The owner had bought it in this state 10 - 15 years ago and since it sounded OK but not very loud he thought this was normal. When he put it up against a Dallas Scala and a Bird Talisman he knew something was wrong! The rest is history. He, like many of your customers is very pleased with the results. Thanks once again for a great service.

Many Regards, David."

 

From Jeremy - Elpico AC85 Amps - March 2007

"Hi John. Just a short note to thank you for all your hard work restoring my two Elpico AC85 Amplifiers. As you know my previous technician had pronounced both output transformers to be down. I was relieved to hear that one was fine. It is rare to find an amplifier technician that can also rewind transformers. Previously I had to get my repair man to remove the faulty transformers and then post them off to a transformer specialist for rewinding. Expensive and time consuming. Your attention to detail is also first-rate. Nothing is too much trouble and you understand how to work sympathetically on old valve amplification without compromising on originality. Both the Elpicos sounded amazing!

Many thanks from a very happy customer!

Kind regards, Jeremy"

 

From John - Music Angel 300b HiFi Amp - February 2007

"Hi John, Sorry about delay in getting back to you. Yes indeed, the amp works fine and sounds very good. Although its not that powerful, it drives the Tannoys ok. It was a pleasure to meet you and to watch you solve the problem with the amp. Great service. I would recommend you to all hi-fi fans who have valve amps that need repairing.

Many thanks, John."

 

From Chris - Gibson Skylark & Gibson Les Paul Junior combos - February 2007

"Hi John,

You've done it again (no surprise). Have just played the Gibson Les Paul Junior and Skylark amps - absolutely awesome - can't believe the improvement especially in the Junior thanks to your superb detective work. The tremolo on the Skylark is now all you said it would be - very Stringalongs (who still remembers them?) so I may drop in that resistor to reduce the depth a touch as you suggested.

Great to see you again and many thanks for the tea and hospitality - unbeatable service.
 
Very Best Regards, Chris"

 

From Dave - Sound City 50 & Marshall PA 20 - February 2007

"Hey John,
 
Hope you are well? Sorry It's taken so long for me to email you. Just like to thank you for the superb job you did on my "Sound City 50 plus " and the "Marshall PA 20" they both sound superb!!
 I'm soon to be off on my travels again, for a few months. I'm sure i can find you a few more projects!! Take it easy. 

Dave "Digger, the guitar-tech" "

 

From Chris - 1963 Selmer Diplomat & Fenton Weill Cadet - February 2007

"Hi John,

Hope you are well? Just to let you know the amps sound absolutely great especially the Diplomat, so will probably end up selling the Cadet. Have upgraded the Diplomat with a 20 watt handling early Goodmans Audiom 61 which sounds even better than the Fane.

Once again many thanks for resuscitating two great vintage amps; look forward to seeing
you soon.
 
Best Regards, Chris"

 

From Dave - 1967 Fender Deluxe - February 2007

"Hi John,
 
Many, many, thanks for the repair to my Fender '67 Black Face Deluxe. I don't think that the amp has ever sounded better. I played around with pre-amp tubes and I've got a pair of RCA 12AX7's and a pair of CV4024 in the pre-amp section now. I put in a pair of Brimar Military 6V6GT's and when I checked the bias it was up at 59 mA, I've got them running at about 25.6mA now and it sounds so creamy, just breaking up at about five and a half, really warm clean sound, reverb is superb, really lush Fender.
 
The Les Paul's sound really fat and the Tele has everything, haven't tried a Strat yet but plenty of time for that.The amp has really come to life, what a beauty it is now it's well again. Thanks very very much indeed, I'm sure this amp will inspire me to play more! The next project will be the 18Watt Marshall combo clone.
 
Many thanks for the hospitality, coffee and the care and attention to the fine detail you have given to my amp.
 
All the best, Dave."

 

From Regan - Vox AC30 - February 2007

"John,

I got to use my Vox in all her glory over the weekend and have to say what a beautiful noise it was too. The Vib-Trem is a revelation - why doesn't every amp sound like this?

Great work!

Regards, Regan"

 

From Tim - Vox AC30 -  January 2007:

"John has got my old 1962 VOX AC30 working better than it ever has in all the 29 years I've owned it. It may still look ugly but it sounds beautiful!

I bought my very battered Vox AC30 in 1977 from a second hand shop in Newcastle. It was a time when Vox's were out of fashion, so between me and the rest of our poverty stricken student band we bought 3, very cheaply and I got the cheapest and most battered but it still sounded wonderful. Unfortunately some deranged incompetent had stripped the original covering and modded it. But at least one of the channels worked like they should and it had the Alnico Vox speakers.

I used it on and off with minimal maintenance until it died around 2003 and then I had a bit of a dilemma. If I took it to a repairer they might fix it but really I wanted to restore it to the original circuits and maybe even get the Vibrato/Trem working! I decided to try to find an engineer who was competent enough to restore the wiring and get it working like it should but wouldn't cost the earth. I talked to several but some did not inspire confidence at all, some couldn't be bothered, some wanted a big fat blank cheque and some were willing to have a go but had no experience of restoration. I found John's website and quizzed him about the job and looked at the work he had already done on other peoples AC30's and I finally had the confidence to put my favourite amp under the surgeon's knife (or should that be soldering iron?).

3 weeks later I collected what is still the ugliest VOX on the planet but it now sounded like it should - and some!. The Vib/Trem was a revelation and all 3 channels sang sweetly. It still hums just a little but who wouldn't after 44 years? John uses quality parts and lots of skill, attention to detail and TLC and he doesn't charge boutique prices. He also fixed my son's Impact 60 head and that too is brilliant. I can unreservedly recommend anyone to get their valve amps fixed by John and I will happily ask him to service and repair 3 other amps I have that need some TLC.

Now all I need is to complete the cosmetic refurb on my VOX

Tim."

  

From Will - Sonus Alpha Combo  - January 2007:

"Hi John, just got the chance to listen to the amp properly and it's sounding great; well its never sounded this good anyway.

It's also about 3 times louder than it used to be which can't be a bad thing and, it doesn't make weird noises any more.

Great work, decent price and a really quick turnaround. Cheers John.

Will."

 

From Anton in Italy - Geloso G226A - December 2006:

"....My Dear John, I have always thought that having gotten to known you via your web-site, e-mail and then telephone has been a big luck and pleasure for me but, after the PERFECT work/restore on my two nice monophonic GELOSO G-226-A amplifiers, I'm very, VERY glad to be your FRIEND. First of all, I think I could not give in BETTER HANDS my old amps!! I was always following with big attention all your updating Mails on the restoration as it progressed, and I was often not believing to my eyes when I was seeing all the "old parts" going BACK to live and to SPARKLE!!!   In a few words, your total work/restore is wonderful, perfect in any details, very clear and respectful, up where it was possible, of the original apparances!!

With just two things you've completely changed, naturally informing me before because you're an absolute serious person, they are "the choke" that was placed over the chassis instead inside and this has given a much better total look and the other was "the rewiring of the secondary of the output transformer", in this case for to reach a SUPERB quality of sound, MUCH BETTER then the original response!!! I also think that describing your "meticulous work" is absolutely useless, because everything is CLEAR and VISIBLE in all the photos published in your nice web-site!

Instead I would like to add a last thing about the final result of the sound quality; it's unbelievably WONDERFUL!! I'm a lover of vintage hi-end sound and in my life I have listened to many glorious tube amplifiers, so I know what I mean by real vintage warm tube sound.

The sound that comes out from the pair of Geloso G-226-A's restored by you through my splendid Tannoy loudspeakers, it's absolutely PERFECT, nothing to envy a many expensive and boasted tube amp of today!!!

THANK YOU VERY MUCH JOHN!...We've many other old device to restore, like my next original and rare TELEFUNKEN TRIODE amplifiers!...

Till the next time my dear Friend..... Anton."

 

From Steve - Selmer Professional Amp - November 2006

"Hi John

I had a good session with the Selmer Professional TV12 last night. As usual when I get repaired amps back from you, I am very pleased with it. Many thanks! Quite apart from the tremolo now working perfectly, I do think that the amp itself sounds better - more oomph and very Shads/ Vox AC** sounding with the echo turned up. Maybe it's my imagination, particularly that you have now told me that it is push-pull Class A? Did you do anything to it that would have had that effect?

Cheers for now, Steve."

 

From Tim - Vox AC30 & Impact Head - November 2006

"Hi John,

 Ethan and I didn’t get much time to try the amps out last night but the initial impressions are:

1). The Vox is brilliant - I've just got to re-learn how to get the best possibilities out of it but first impressions are it still has the one good sound I used to get out of it and it now has a whole bunch of other possibilities!!

2). The Impact is a revelation. The bass channel is great but, it makes the Celestion Greenback speakers flap a bit at 60%. The Treble channel is a fantastic 70's style distortion at 50% and this is before I've had time to put the JJ EL34s in.

I look forward to a more detailed try out at the weekend. Thanks very much, from two satisfied customer’s, I'll be in touch soon with the additional pictures and comments later.

Many thanks for your hard work, time and effort, Tim."

 

From Adrian - Fenton Weill Porta Bass - September 2006

"Hi John,
 
Don't know if you remember me. You repaired my Fenton Weill Porta-Bass amplifier for me. Just thought I'd say thanks for your hard work and also to send you a photo of the finished re-covered amp in full working order.
 
Thanks again. Adrian"

 

From Karl - Gibson Skylark Combo - August 2006

"Hi John,

Just to say how pleased I am with the work you have done rescuing the Kalamazoo Skylark. It did look as though there was a great amp waiting to emerge from what arrived from the USA, incomplete as it was. The work you have done exceeds all my expectations particularly as the amp has not been modified or changed in any way other than for safety. The amp looks great and sounds stunning I imagine just as it did when it was bought in 1964, if not better? Why these amps haven't got the kudos and collectability of Fender Champs is a mystery and lets keep it that way. Cheers again for your painstaking work. 

Karl" 

 

From Justin - Wem Westminster Combo - August 2006

"Evening John... is that whisky flowing yet? What's your poison anyway?

Just wanted to say thanks for the work that you carried out for me earlier today. I've been playing through the WEM all evening and absolutely love it. To my ears its got a lovely warm tone and no more crackle and pops! ;-)

Thanks for letting me call in today and stick around while you diagnosed and resolved the issues - it was very interesting to witness the process and learn about your other projects. I also realize that you went out of your way to save me effort, time and money - you're a rare breed, thanks. I hope you managed to get to the garden centre for your mum before closing and got everything sorted?

Thanks again John.

Cheers. I'm off to buy another doggy amp!

Justin."

AND...........

"Hi John, 

Hope you're well on what's suddenly turned out to be a sunny Sunday evening down here in Worcestershire! Its been rather cloudy all day. Anyway, as promised, please find some photographs (I've included a few for you to choose from) of the Wem Westminster you revived before my eyes at the "Amp Hospital". Take a look at the pictures and let me know if they're suitable or if you would like anything in addition.

Once again, I'm absolutely delighted with the results following your meticulous service and repair of my beloved Wem Westminster. Thank you.

Cheers for now. Justin."

 

From Cliff - Bird Golden Eagle - July 2006

"Hi John,

Just a brief e mail to say thank you for performing miracles on my old Bird amp, the difference is amazing and to my ears it sounds as good as any amp out there, both vintage and modern. When I first made the journey down to you from Preston, I was just wanting to get the amp repaired and working, (something that other amp technicians weren't prepared to take on), and I was therefore absolutely delighted that not only did you get everything working properly, but you have transformed its performance. I would imagine that the amp sounds better now than when it was brand new!

Once again, many thanks. Kind regards. Cliff"
