VT-73 Motorola Sound IN video?

[koviatt]

Hello all. I have recapped a VT73 recently and am having some difficulty getting things playing properly. When I fine tune the set I can get either decent sound OR decent video. But never both. If I attempt to align the set I can get both together but the sound has a terrible buzz (more than normal) and with volume set high it trashes the video. (It modulates the video). If I back off on the audio the video returns to normal. But then I cannot hear the audio. I think my problem is alignment related. But I cannot seem to get past the first alignment step using the Motorola service manual. The waveforms just don’t look at all like what I would expect so I just decided to align by eye and ear and have video peaked nicely but the audio is missing. Or vice versa.
