Front view, and yes…..it does have a clear “see-through” Perspex panel.

Rear view - The KT88 retaining hammocks were a necessary addition by myself. When first removing her from the packaging, I found that both the original (replaced) Svetlana KT88’s had fallen out of their sockets during shipping, and one of them had to fall onto the concrete part of my workshop floor. And…….yes it smashed!

Out…..and ready to make a start.

Oh no…..PCB’s again! Now, not only do I dislike PCB’s in tube/valve amps but……this one really does take the ****! The small tube bases are fitted to the chassis from the top, and then the main PCB is laid/fitted over the bases with holes in the board for them to protrude through. Now, all nine pins of each tube base are soldered with short “fly leads” to nine small turret tags. This means that not only does the top board have to be removed in order to gain full access to the bottom board but……..all thirty six bloody wire links have to be removed too, before the bottom board can be withdrawn from the chassis!.......what a heap of crap!

As above…..left-hand side of the chassis.

Close-up, everything out and all cleaned up ready for re-fitting.

Just look at the state of this thing….an engineer’s nightmare!!

Virtually finished….at last! Just the knobs to do and, she’s now looking and sounding pretty good too! This amp had been worked on many-a-time before, leaving all the wiring really butchered and untidy. I sorted this issue out too as can be seen in this photo. My advice to anyone contemplating buying one of these is….stay clear of them! But to be fair, now she is all back to rights, and it does sound pretty good.

Chris, the owner, has since re-covered the amp as he didn’t like the “croc skin look” plus, it now matches his home-made speaker cab. I think he has made a very good job of both of them. Below is his testimonial e-mail and a photo of the amp….as she is now.


"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 yourself and keep doing what you do best!

Best regards, Chris."
