Wow, Thanks Callan! I never thought it could be the yoke - I'll have to
check. I looked very closely and noticed the heatwave is a slight variance in
deflection. This goes from the top to bottom of the screen (on Tempest), so I
was thinking checking/replacing Q705 (3716) and Q706 (3792). The "heatwave"
is actually the beam moving up a 1 pixel in different areas of the screen, so
I was really thinking it might be in the Y amp...
Anybody have any other ideas??
I'm going to check Callan's yoke idea right now, and I'll report back the
results.

Thanks,
MK
