You really need to convince your resistors to stop smoking lest they die a horrible untimely death.
Seriously, note well advice about speaker field coil and output transformer being hooked up anytime you run the set. If either one is bad (open or shorted) stop. It's only going to get worse if you don't.
I have a few ancient analog DC ammeters to have a look at the current draw. My favorite is the 500 MA. If it goes way up, I rip the plug out and find out why. Got larger and smaller ones too, depends on what I reasonably expect to find. Red terminal to positive side. OK?
