Looking at your 4-Knob Model 20 page, that wax-paper cap (yellow) I don't believe would have been comtemporary for the model 20 in 1930-31 as available parts. Appears that this "add-on" tone control was added not long after the set was new.

That capacitor would have to have a voltage rating of 1200 volts to safely withstand the audio AC peaks on those plates.

Intersting find. Icon_smile

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