Already plugged it into my Quantum - exact same problem.

The deflection board on the monitor giving me trouble is a P327. That
is also the same revision board that is in my good monitor.

The board has the multikit in it, so it has revision 3.

Yes. As per my previous message, this still occurs. I have made the
screen as small as possible using the adjustments on the Tempest board.
If I move the picture all the way up so that it is on the top half of
the tube, it pretty much looks okay. If I move the picture down, the
lower right quadrant is always screwed up. It's always that corner of
the screen.

Okay.

Looks like I'm part of the .01% :) Is it possible it could be a problem
with the input protection on the deflection board itself?

Yup, I realize that the input protection circuitry can cause a problem,
however both boards that I am testing are the same revision. One has
the problem, one does not...
