I think I found out why. Apparently tube amps like their power caps to be in tact. This is the power board on my peavey butcher. totally makes sense why the noise was so loud. probably also prematurely wore the tubes out I had in it, which would explain why two of them died in my mesa the other night.

wow. peaveys are hardcore.
Im fixing it tonight.
also learned a neat trick. home made solder wick with some coax cable. strip the cover. then pull the interior wire from the copper braid. dip braid into flux and bam.
I'd be curious as to how that shit happened.
No clue. I think the joint fatigued and maybe the amp got jostled. It got bent when I was pulling the amp out of the chassis.
Has the wire come out of the end? Some caps are made to eject the wire when they overheat, rather than full on explode like others do. It could well have jsut been going a bit wrong so noisy as it overheated and eventually totally went. Kind of why should fix amps when they start misbehaving rather than keep using them and wrecking loads more components.
