Default Re: Servicing 'Secret Listeners' radios in the 2nd World War

I do not know what actually happened, but I suspect that the sets involved were relatively simple and that most likely faults were found by simple substitution of valves and perhaps other components.
Supplying an Avominor and spare parts would probably cost more than a complete replacement radio.

Some users would be able to consult pre war textbooks, and MIGHT have had a test meter.
