Hi Group,
My current project is repairing a 8558 SA and its 182T mainframe.
The mainframe has an X problem, the bottom half (on the schematic) of the X push-pull amplifier has a low output voltage instead of 50V, ?4 transistors and some resistors have been checked: all good. Still looking ...
The 8558 has a frequency display problem, it displays "+1" instead of the frequency, I will tackle this one later.
If anyone has encountered the same problems, I am listening to your wisdom.
Best
Jose
