CHAMP ELECTRONICS -" THE VINTAGE VALVE
AMP HOSPITAL"
NOTTINGHAM, ENGLAND
SERVICING A SELMER STANDARD
(TV8/T) 5 watt
COMBO AMPLIFIER - CHASSIS ONLY
I have included this second
Standard TV8/T as it has a slightly different layout to the one in the
preceding article. It was brought to me as just the chassis, and it
needed quite a lot of attention/components replacing, including an
“open-circuit” output transformer primary winding. Hence no
output transformer is shown on this photo!
Underside
before any work. There were that many caps needing replacing on this
one, and a few resistors. As everything is “wrapped” on
these, it makes better sense to just simply change virtually
everything! Also, notice how this one is built on a tag-strip rather
than a group board, like the one in the previous article!
Both
input jack sockets were very hit ‘n’ miss too. Here they
have been replaced and are being wired on the outside of the
chassis…..much easier to work on them like this!
The rewound output transformer back in place, together with a few new components and two replaced tubes.
All finished. Looks pretty nice & neat too……cool!!
Here is the customers (Ashley) testimonial e-mail when he got his amp back home.
"Hi John.
I
put the amp back into its cab last night with the original speaker. It
sounded very nice, so thanks for the great repair. That tremolo is
unbelievable! Later on I connected it to the speaker in my Line 6 amp's
Custom Celestion 12", 8 ohm, 75watt, and it sounded absolutely superb -
it takes the bass up and the treble down, and when turned up fully
gives a classic 70's "crunch", the sound I really hoped for!
Once again, many thanks. Ashley"
