Many thanks Bob, you seem to have hit the nail on the head with that. Took the volume pot out and saw that there is an earthing washer connection between it and the chassis, as detailed in build instructions I now see. It all looked quite oxidised and the solder on washer was also interfering with the connection, so filed it flat and got some emery cloth on all the mating faces and screwed it back in tight. Checked continuity which is now good.

Have had it back in system playing for about an hour and all appears well, in fact it seems to have solved both problems.
