Poor IF alignment could do that, but there is also a resistor in the local oscillator circuit that can cause that if it goes off in value, this is with the usual pentigrid convertors like a 12SA7/12BE6, I think it's around 47K ohms, or possibly 22K. If it isn't either of those things start looking for faulty mica caps in the oscillator tank circuit, if there are any, some of those post war micas were of poor quality and can go bad.

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
