The power transformer is not bad, the ballast is bad.

In any case the transformers can be rewound for $160 if that (i.e.
an expensive radio!) is your "thing".

But then what about the ballast? I MAY be able to fix it with my spot
welder.

Are they available? Could I just use a fixed resistor? It looks to
be wound with Nichrome wire or plain nickel. These have hugely
different temperature coefficients. Presumably a light bulb
of the correct type would also work.

Does anyone know what the resistance is under working conditions?
Does anyone know what the voltage across it is under working
conditions?

Today is tar-pit melt day.

The strange open mica capacitor is good. The wire resistors
on the board in the power supply are good. Two of the wirewound
grid resistors are bad. Is the inductance of these of any importance?
All of the glass resistors are bad ... in fact, the glass is loose
so I removed the carbon and cleaned them up so I can leave them
in place.

Oh yes ... it looks like the case inside was painted tan. Does anybody
know if that is true, or what it really was? What about the steel
mount for the tube sockets?
