My amp died last night
it's a 90s OTR120 combo
Complete volume loss and no glow in 3x power tubes
Any ideas what might be the cause? I want to cry

Bad tubes?

I hope so.
They were replaced about 4 months ago and it's not been heavily gigged or anything.
I always assume the worst with this amp, had to have a new transformer in May, valve socket damaged, damp, chassis rusted, damaged speaker coil, over heating and it stank.
Thanks and here's to hoping it's that simple!

I'd have a tech go through it all. Clean and re-tension tube sockets, which could be oxidized if you're saying the amp was damp/ rusty, etc.
Could be tubes, could be not getting the connection they need.

How is the amp damp? Is it makin its own juices? Was it left somewhere damp? What killed the transformer? Does the wiring inside look okay, or does it look messed with?
