We have a little progress. Jones Plug pin 2 had frayed wire, and a single strand was fouling pin 1. Resoldered and applied heat shrink. But no real change. I then tested the radio, which I had neglected to try previously, and the volume was just the same as always (no.2 on the volume dial).

So can we say for certain that the fault lies in the Phono preamp circuit? Will have a look at the schematic, they are not yet second nature to me so would appreciate suggestions.

Re the clamp on C2: The angle of the photo is deceiving, the lead and clamp are not in contact. It does look like it but I think that is because of the limitations of the phone camera. I have checked and there is no contact.
DAD UPDATE: No surgery today, but they are saying he is on the list for tomorrow.
Cheers from Bill.
