Amplifier Restorations
Old Sony STR 333L
This 1970s tuner amp came in Sony STR333L. Owner wanted it brought back to life. Had a twiddle with the tuner knob (amplifier's not the owner) and realised that the dial cord was broken. God I hate ...
Ampeg Power amp
This big brute of an amplifier came in from a local guitarist. Sounding very distorted, a quick scope checked should one half of the output stage not working. Thankfully, the output transformer was ...
Pye Black Box
Not seen one of these for ages, the a customer brings in two. I never really got to the bottom of how many variations on the black box amplifier there were. Different controls, different valve line ...
Musicson
Get a lot of old PA and group amplifiers in. Some, like this one have been round the block a few times. This is a Spanish built amp. probably going back to the late 70s early 80s. Straight forward ...
Trace Elliott big boy’s amplifier
Local musician brought this amplifier in. Not a lot wrong, but some puzzling things. Open circuit fuse holder? Couple of resistors way out of spec. Strange as the parts used are good quality ones. ...
Telewatt VS56

Leak Stereo 20
Okay Boys and Girls. Nobody argues here. Right??? In my opinion, probably the best amplifier to come from the UK in the 1960s. I have restored many of these and have never been upset by the quality ...
Beard P100
Now some people say these amplifiers were unreliable. From a personal view, I like them. They sound nice, well made and have a good damping factor, controlling big speakers well. Ok, this had a few ...
Leak Point One, TL12…. Et al
Well, you can't say a bad thing about any one from the Leak family (no, I am not talking about the Leak 30s and 70 please). What to watch out for; Have a look at the mains transformer for signs ...
Audio Research
I have had a couple of D115s recently.These are lovely amplifiers, but not designed to be serviced. Nine 6550s / KT88s and loads of drivers, phase splitters, long tailed pairs, ICs, transistors ...
Pye HF25s.
These amplifiers are quite rare today. They did not seem to be as popular as the Leaks and Quads, but were equally as good and very well made. This was mainly due to PYE's set building for the ...
