Re: AVO VCM MkIII repair
Have you read the service manual for the AVO Mk III? If not, download it from the forum or elsewhere on the Internet, and read the chapter on how measurements should be performed and what measurements to expect.
In the Mk III you have full sine wave signal on the Anode voltage and half wave rectified voltage on the Screen and Grid.
If I remember correctly now the service manual says that you should short the rectifier valve in the Screen circuit when performing those measurements.
Since the relay was a problem and you had it removed you might have to check the wiring as it might be incorrect.
