Peavey classic 30 tube amp no sound.

Really 230? Is that standard in UK or you have to run a dedicated outlet? Ok won't turn on but for testing purposes if I want to test outside of cabinet what I. Particular is wrong with how I have it? I was thinking of proping it up between two wood legs so I could put the tubes in?

The right cap is way more noticably blown.

Damn I just wanted to make some noise not go into tube amp repair mode. I can't afford a professional at this time. Im decent with a soldering iron at least

So with my incredibly limited understanding of analog circuits I'd say it's likely that C40 and C39 being blown could reasonably result in no sound at all from this amplifier not even static? Anyone disagree? This is actually the most complicated electrical schematic I have ever put any time into so it is basically nonsense to me though I would like to understand it. Can anyone tell me what the purpose of both these capacitors is, like what makes them a pair? Is it related to polarity?

C39 and C40 may not be "blown" as such, they may just be leaking and need replacing.
If the fuse has not blown and the diodes are ok, then there may well be something further downstream that is not working.

So C39 and C40 may be a problem, but not the one that made a burny smell and broke the amp.

Dang that's what I was worried about! It is a possibility, though I think unlikely that a metal clip that works as a thread for the bolts that holds in the board created a short that caused the damage. I noticed it was loose when I opened it up, but it wasn't anywhere near the blown caps and was close to where it came from. No fuses are blown the diodes all tested out nothing else appears burnt or is visibly damaged. The smell was not the smell I associate with a shorted circuit, in fact it didn't really smell at all just smoked a bit
