Re: Marconi 702. Sound problems.
That was an easy fix. A wire had become disconnected from the grid coil of the X41 frequency changer valve. The sound was restored but was distorted and there was also patterning on the picture. The oscillator trimmer has two positions, one with the bad sound and picture and the correct one which is completely free of any defects.
