I'm having this awful, randomly occurring noise coming from a JCM800 2203. it sounds like feedback almost. really loud, ear piercing feedback. or like something heavy is falling and smashing to pieces. but it doesn't happen all the time. just for a couple seconds every minute or so maybe. something like that. anyway. i poked around beneath the chassis to see if i could find anything out of curiosity. underneath the v1 preamp socket, the lug for pin 2 seems looser than all the other ones. like if i pulled on it hard enough, i could pull it out. also...probing it seems to affect the bad sound i'm hearing.
now my question is, could the loose lug be causing the noise? if not, what could it be?
i was going to replace the socket, but before i did all the work and bought the new socket, i wanted to see what other people might think.
