Default Re: Vidor CN429 'Lady Margaret' fell silent

Vidor's switch is an odd affair, different from any other one I've seen. Its contact is a piece of copper that's spring-loaded. If that contact has any corrosion, there won't be any voltage.

Can you tap the tubes while the set is on and see if you hear a "pwong-pwong" sound from the speaker? If so, you have good audio and something's went wrong in the radio section. If no "pwong-pwong", and the batteries are fresh and delivering the proper voltages, then I agree--output transformer's open.
