Hello again.

Before going much further, I am very suspicious of the -12V supply. If that is seriously low, or not connected everywhere it would account for almost all the problems.

Check the voltages on the regulator 79?12. You should get about -15 to -20 on one side, and almost exactly -12V on the other side (connected to the test point 'blob').

It wasn't me!
(Well, actually, it probably was)
