How is the screen geometry?
I would check the various voltages to the CRT except the acceleration
voltage with a medium voltage probe.

Hi,
I have two 7623b with the following
symptom: Focus adjust perfect on the
center and not so perfect near the edges
so when readout is perfect for astig/focus
the center is bad and vice versa.
Not too severe on one, but quite bad on
the second scope.
I'm sure someone will know ...
so better ask before I tweak them up too much ;-)
Many thanks.
