Hey guys, I've got a '65 Bassman that was making a lot of noise. I replaced the electrolytic caps and cleaned all the pots. Now, at least the pots don't add to the problem. When I take it off standby, there is a 'pop' and then a sound akin to radio static. When I shut it off, it takes a few seconds for the static to go away. I'm figuring plate resistors and coupling caps next - but I've gotten great advice from this board before, so I'm hoping you might have some suggestions as to the cause? I've never heard one make a noise like that when it's powered off.
