Hello Terry,
Thanks for the reply.
I'd really like to get the diagram to verify the power transformer filament line up and the power supply section. The 425 has the same tube high voltage rectifier as mine ( the 470 ), while the 460 has an 1V2. So I think my wiring diagram ( at least for the power supply section ) is quite similar. Before I put in a replacement power transformer and power things up, I would like to make sure !

Its surprising that the 5y3 high voltage rectifier even worked as they were used probably at their very maximum voltage specification.

Regards,
Daniel

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
