Hey I have a peavey xxx that has had blown out powertubes twice now since December. I take them to the shop to get done so I trust that they are being done right. I never mess with them myself, and keep it in my house whenever I'm not gigging with it. I was just at practice and I smelled something burning so I looked in back, and the 3rd and 4th tubes were glowing red. When I turned it back on I didn't get sound and the 3rd and 4th tubes weren't glowing as much as the first two were. When I got home from practice an hour later I plugged it in and it worked fine clean channel wasn't distorted or anything. What do you suggest I do? Also, If you're into metal check out my band myspace.com/sentinelshred

Based on what you've said "I smelled something burning" and "tubes were glowing red" it sounds like you've got a short circuit somewhere in the wiring. When you plugged it in at home, did all the tubes light like they're supposed to? Clean sound is easy to do and if 2 or 3 tubes are out, it'll sound pretty much the same. The other possibility is that the wiring at your practice space may not be grounded and so your amp may be getting more current than it can handle. I'd try a surge protector and if that doesn't help, take the amp into a shop and have them check the wiring inside.

If your shop that you go to is any good, than they should at least consider a small fraction of responsibility for that, especially if you ever brought it up to them. Obviously, it shouldn't eat the tubes that fast, unless it is constantly on, ha.
But if you don't get any intelligent and pro replies on this, than you should take it down to your shop or see a different specialist to find out what's wrong.

Yea I use a power-conditioner, it must be poor wiring somewhere in there. Although they supposedly have fixed the wiring both times because they were bad.

Hm. How's the haul home? My amp's wiring wasn't the sturdiest thing in the world, and when I took it home, it was like it wasn't repaired at all. Maybe something got messed up from getting bumped around in the car... Just an idea.

Are they EL34s? I've heard some early runs of XXXs had problems running those, due to a crappy resistor somewhere.
