LOL It was inevitable.
I have, for years, ran it dimed (or at 8,9 on vol); typically into a load box and tapping the signal via line out.
Popped HT fuse and 120Hz hum. Once, popped mains fuse.
So now, troubleshooting... have me a lightbulb current limiter, multimeter, spare can caps, taking measurements (drain those caps first!).
Could be a blown OT, choke or both... I'm already past the "easy check" part of troubleshooting (tubes, etc).
We'll see.
I'm not freaked out because I built the thing, and I needed to get back into the guts after a handful of years (last modding session) to re-familiarize myself with the circuit.
I'm actually going even deeper as I learn how to conclusively test the OT to see if it's good (6.3v filament transformer test), choke test, maybe ever PT test, etc..
Learning is good.
