Hi Joe,

A blessed and meaningful Memorial Day to you also.

Try this:

Remove all the tubes. The voltage across the filament string is 7.5V. Current in the string is 0.05A. If E=IR, then R=E/I. So 7.5V/0.05A = 150 Ohms.

Remove the tubes and tack a 150 Ohm resistor best to use at least 5 W. between pin 7 0f the output tube (3V4) and Pin 1 of the convertor (1R5). Plug the radio in and measure the voltage across the resistor and the other power supply points. They should now match the schematic. If the voltage across the resistor is 7.5V +/- about 10 - 20 %, then then replace the tube(s) that have open filaments. If the voltage is significantly higher 9V or higher), then troubleshoot the power supply.

I assume that this radio never worked since you had it and since someone tried to fix this before, then only the Dear Lord knows what happened beforehand.
