[R-390] Help with R-391 needed

[Tisha Hayes]

It sounds like a shorted capacitor somewhere in the receiver.

I would pull all of the tubes (except for the rectifiers) and isolate the
decks (if you can) and go through the exercise of lifting one leg off of
every capacitor on that power string.

If you wanted to be nice to your transformer and power supply chokes you
could use an external bench supply to liven up just that circuit, put a
series resistor on your power supply to current-limit whatever is shorted
as you go through this process (no reason to do the smoke test). If there
are convenient places to break the circuit in to segments it will help
isolate the fault.

Divide and conquer.
