Magic smoke can come from anywhere so finding the general vicinity of the source is key to diagnosis.
How would I variac the radio out of the cabinet? I can't run the radio outside the cabinet because of how the interlock plug is made on this radio.

Also I had figured out that the diode I wired into the radio to replace the selenium rectifier shorted because I wired it in backwards unintentionally because I was wiring it up how it was on the selenium rectifier which had the cathode marked with a (+) sign which made me think it was the anode side because of how it was marked.

But the only thing is that when I replaced and properly wired in properly, there was no audio but the tubes were lit.

What would be going on?
