Just as a side note: the landlord/owner is the one who must obey City Law. First kindly ask him to update house wiring, out of his pocket of course. If he sharply denies it several times, then you go straight to whatever City office handles that. Which unless the landlord is a total moron won't hap...

Hey, sorry to be that guy, but someone's gotta say it: Playing or working on this amp without a grounded chassis is foolish. I just want you to live to see 2016! I certainly don't like it, but there's no option other than plugging to one of a few GFCIs. I rent, and I'm in a city that is very on top...

If you have something that's grounded nearby, like a cold water pipe or a radiator, you could run a ground wire from the adapter to that. It'd buy you some safety margin and maybe lower noise.

Gotcha. Thanks guys. I think I'll keep it simple for now and try not to do much more than get the thing running again and beef a few things up like Steve suggested.

That's all very helpful, thank you! You also confirmed my suspicion that the amp has been worked on before. When I started looking up info on them I noticed that I was missing the rear grill for the cabinet. Unfortunately I don't know that I'll ever be able to find out why. My brother gave this to m...

Hi everyone, I hope I've found the right area to ask this question. I'm hoping to get some opinions on why my amp practically caught fire today. There's not much back story. Amp seemed fine at the store. I carted it home last night,and this morning I plug it in, flip it on, and head to the bathroom ...
