As for the power transformer where the wires exist the bottom is there a bunch wax or tar? Is the chassis all yellow/brown colored around that part of the chassis? If not just remove the 5U4 FIRST plug the cord in and turn in on. If the lights go off in the room there's a problem. If the remaining tubes light leave it on for 5 or 10 min and see if the power transformer gets hot to the touch. If it does that's not so good. Probably shorted.
Check the hvac from chassis ground to each plate of the 5U4. Voltage should be within a few volts of each other.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
