  When I acquired my monochrome system in July 86, I did notice an
occasional jittery. Also a white ghost band (1/4 inch) would appear once
a while from left to right near the top of the screen. I returned the
monitor within a week, and the replacement I got (SM124) hasn't given
me any problem since (not even jittery).
  With regards to skewed display, etc., one can quite easily open up
the monitor and make some adjustments. If you look at the deflection yoke,
it's held by a single screw located at the neck of the tube. Unscrew it
slightly, gently turn the yoke as approppriate, then tighten screw again.
Right by the screw are two deflection levers; these shift the image
horizontally. To enlarge the image, adjust the white plastic screws located
on the bottom circuit board of the monitor. (All these pertain only to
the SM124 since that's all I have)
  Opening the monitor will VOID the warranty.
