I seem to remember that Jeff Hendrix had this similar problem with an
ampliphone. It turned out that some wire (might have been the HV wire) off
the transformer was loose. I am speaking from faded memory here though.
Perhaps Jeff can remember. If you could stick a scope in XY mode off the
PCB outputs and they are "clean", then your jitter problem is the monitor.
