Seems to have cured the problem again, just wish I knew exactly how and
why.
Will have to wait until a PR772 circuit emerges out there, the input line
goes off simply to a TL072 but there is compexity around the ground lines
and chassis



Just ask Fender for a schematic. They are very helpful and will send you one
for anything that's not already available for download on their website -
which almost everything that they've ever made already is. Last week, I
needed a schematic for a "Deluxe 85". This is not on their website (UK or
US) and the only one 'out there' is with a site that wants you to pay them.
I emailed support on the US site around lunchtime here, and by late
afternoon - presumably as they opened up shop a few hours behind us - I had
a reply back from a friendly engineer called Bryce, with a copy of the
schematic attached.
