Thanks,



But now Murphy came calling as I lost all triggering, so have to back up

On the collector of Q904, I have -0.865 volts when I should have +0.5
volts.


In the 465 and 485 scopes the A and B sweeps are identical. If the 475A is
the same, you can try switching components from one to the other, one by by
one, and see which one causes the problem.
