No hum, no noise, nothing... to be honest, it doesn't even have time to warm up the tubes to put out any noise. It happens almost instantly. I get maybe 5 seconds after I hit 90 volts on the variac, and there is smoke. The rectifier tube tests good, which doesn't mean much. The only weak tube is the 42, which I think is the output tube. It's not a bad tube, but I'd typically replace it once the set is up and running. Nothing else gets hot, just that one electrolytic.
I'll look for a short in the B+.
If you look at the photo I posted, No 47 is a big wire wound resistor. Very easy to find, very easy to trace the wiring. I've got both negatives running to 47, and I've double checked it 20 times, so I hope polarity is correct.
