Hi, I'm back with a new password.
I would like to thank the people who replied re 32v radios

One member mentioned that I should leave my email, which I will here, also I made Astor HMQ comments in the Intro forum...i have a fried one...not beyond help I think.

Thankyou all many regards Michael.

But what in particular did you fry? Those valves are not very tolerant of over voltage on filaments.

The only thing different with these things, is the power supply. The main body of the radio fails all of the parts an AC one does.

The power supplies are predictable. The last vibrator type PS I repaired was in an Airchief.

I wish it just fried some valves...i wasnt there at the time, but should have known something was up when Dad told me he had to switch a few lights on to get the radio to work.
A quick glance ( total novice) under chassis sees 1/2 dozen wires around one of the valves with melted insulation and a puddle of wax on the floor of the vibrator box from what I assume is a capacitor.

It never ceases to amaze, as to the damage those who know nothing about radio's can do using their expertise in trying to get a set to run.

One can only hope that the caps took the bulk of the load. The tube filaments can be checked for filament continuity with an ohmmeter. Because in filament valves the heater & cathode are the same I can visualise them cooked.
