Hi Paul,
I have the 070-9096-06 manual.
I hard a good look and found the wire, I think some one has adjusted it before and now its flattened to the PCB.
My instrument does not pass the amplitude normalizations. So I decided to start going through the adjustment procedures. When I measure tp300 which should be between 8.5v and 9.5 it is about 10.1 volts.
I can see the calibrator signal , so I thinks its locked, but reading though the adjustment procedures, I noticed that it keeps mentioning C204, which in my case is a wire, but I cannot adjust it, because its flatted to the PCB.
Regards,
Alfredo
