Hi
I've recently aquired an early 60s all tube/valve hand-wired SE Shaftesbury 519 combo. It has all its original tubes, transformers and alnico speaker which is probably celestion.
It has a tremelo circuit and once would have had a footswith with tremelo on off and depth control.
When I got it, the volume was low and weedy on both channels and the tremelo didn't work. I've replaced all the caps and now the tremelo works, but there's a loud thud for each wave of the tremelo when it's turned up.
When I use an ordinary footswitch to turn the tremelo off, the volume doubles and there's a wonderfully responsive pure class A overdriven sound.
Does anyone know where I might find a simple circuit for a footswitch with a depth control and also is there anything else I can do to improve the tremelo circuit?
