amp smoking

Brian blaut · February 9th, 2008, 05:18 AM

We have a little battle of the bands going on at work. There is a permanent community 'band' area with a small assortment of equipment donated or left there by the owners for work play.

I went there to practice with my rag tag cobbled band of co-workers and found the amp I usually play through was gone. In its place was a tattered, well used twin. I turn it on, let it warm up and start playing. After about 5 minutes, my sound cuts out, the jewel light is blinking on and off then it just goes out. 30 seconds later, smoke starts coming out of the top right corner. Obviously I shut it all down, unplug, etc...

So amp guys, what happened here? Cap or something go bad?

Probably a tube went bad taking some screen resistors with it.

this same thing happened to my little magnatone amp, except the jewel light stayed on.

amp started smoking, and no sound.

tubes still light up though.. dont want to steal the thread, but any ideas?

Could this also be a power transformer? I've had that happen to a couple of Champs over the years.

Power transformers usually stink like hell when they go, my bet would be tube/resistors.

Amps run on smoke. When the smoke gets out the amp stops working.
