If you look closely at your broken socket, you can trace 2 of the wires back to chassis ground. Those are your radios (A- & B-) solder them in together to chassis, your done on the (-) hookup on chassis.

wooopsie! B-minus will go to the chassis via R11, 390 ohms. Make sure this resistor is actually in place. In some designs it was part of the battery plug. Its the bias resistor for the whole radio.

IF can wire size and Rubber mounts?
Renovated Radios do carry what you need. As for the voltage, a wire should be at least 300V-rated.morzh — 11:13 PM
