Trouble shooting the non functioning trem now

Plate voltage to v3 pin 6 on and off with push pull/foot switch for trem and I can hear a faint ticking that comes and goes as youd expect with those manouvres. The ticking responds to speed and depth controls but no audile tremolo in guitar signal. Could be a cap?

[StrummersOfThunder]

Im thinking ill change out the old cap can ( if I can find one) the grey 50 and 25v electrolytics and the large 450v 16mf electrolytic.
The trem phase shift oscilator caps tho are probably whats gone wrong im picking? Jean is going to reverse engineer the schematic which will help a lot.

Just vibes here but lead dress may help or biffing a cap somewhere. I’d be looking up how to solve the tick in deluxe reverbs and see how you get on porting that over

Oh wait youve got the wrong end of the tick

Im welcoming the very very faint tick as it means the circuit is doing what it should. I wont be audible at playing you really have to strain to hear it.
Tick doesnt need solving. And its a loaded word with trem stuff. But its been valuable as a guide to see what switches are working/pots working etc

Dirty Harry always got the shit end of the tick.

Cap can question:
calls for 40 40 20
Cant find one but can find 40 40 20 20
Guessing I can just leave on unused? Or is it better to get 40 20 20 20 and tie two together to make 40 ?

[Jay]

I doubt the 40/40/20 is faulty. You said the amp was quiet so that means power caps are fine. The caps for the trem should be fine too. As Tony says, I would resolder the components in the trem circuit first.

In a highly technical discussion among experts about the technical function of an electrical circuit, this has to be the most useful contribution I've ever seen.

When the trem in my old AC15 died it was a burnt out resistor to blame, worth checking them with a meter?

Oh I’ll be checking them !!!
