Got home from work, turned my tube amp on standby to warm up while I ate dinner.
House randomly started to smell weird almost like chlorine. When look around my house and even the attic, didn’t see nothing. The smell was strong from my entertainment room and notice the standby light on my amp wasn’t on anymore and the smell was coming from the amp.

Before I open up the amp, any ideas on what just happened?

A capacitor on the board burned out. Need to do a cap job or buy a new amp.

Burnt capacitor or resistor. I think someone said that already.

More concerning thing would be if something caused it. If the tubes are weak I think it can put extra stress on it. I think capacitors are supposed to last 10-20 years? Not sure of your situation.

If you wanted to get your hands dirty you could use a signal tester and go through the circuit and find the faulty part, but if you’ve never worked on an amp or circuit board before I wouldn’t touch it.

I’m a keys player, so I haven’t worked with amps, I’ll tell you personally that I’m inexperienced and I tried to fix / restore my Wurli and deeply regretted it because I went the whole way, refelting the keys, removing the speakers so I could spray paint the top… what should’ve been a $350 job turned into an $800 job. The circuit part was the easy part honestly.
