Hey guys, so during band practice (of course) my amp just stopped making noise. I saw that the power light was on, but the standby switch light wouldn't turn on no matter what I did with the switch. I looked the back and saw 4 tubes and they were all glowing, then I check the fuse and it looked fine. Any ideas as to what happened?

Nope. Feels all normal and stuff. It's bothering the crap out of me. My friend has an uncle that works on tube stuff all the time, and he's gonna take a look at it tomorrow, but I just wanted to see what UG would say.

I'm going to mostly agree with LeviMan. Most Peaveys that I've worked on use push-on connectors for the standby switch. One of these may have come loose. I'd start there and move out from the standby switch.
