Anyone ever heard of a microphonic cap? I have a 2204 build that sounds like a valve is going a little too microphonic. Tapped all of the valves and it’s v1, but it does it no matter how many valves I swap in. It’s the only socket that does it. No static or popping, just high microphonics that you can hear through the cab. Valve is a little loose in the socket, so if I can find time tomorrow, I’ll pull the chassis and re-flow the solder (just in case) on that socket, retension the pin holes, and shoot it with deoxit. But I read somewhere that caps can go microphonic??? Coupling or bypass cap for v1 maybe?? Anyone else ever had that?
