Hello everyone,

I am using the schematic from here, NA. I am wiring this radio as most of the original wiring was missing.

I do not think that the schematic is correct with the +45 volt circuit. If you trace the circuit it goes to a junction eventually connecting to the Battery Setting 6 volt input to the + side of the filaments.

I do not think this is correct.

Does anyone have a schematic that shows something different or can answer as to how this supply should be wired?

Information and solutions appreciated.

Hi Mitch,
The schematic looks OK.
The thing that is throwing you is that the 6 volt positive is common with the negative of the 45 volt supply.
The negative of the 6 volt battery is distributed to the filaments through a variable resistor.
