Having not worked on vector monitors before, I am having trouble locating the HV diode. I looked on the parts list, but it seems that none of the
part numbers are in there (or I missed it). Can you guys fill me in on the location and how to recognize it?
 
Thanks,

Dave,
Diagnosis is pretty easy, repair is pretty easy, but the part is getting harder to find. The symptom is called (at least on this list) "blooming,"
and it seems always to be caused by a failing HV diode. It can be replaced with an sk7333, an sk7330, the original Varo h1812, an NTE527A,
none of which are currently in production. The 7330 and the H1812 are drop-in replacements. Rodger Boots posted less than a month ago that
he had 2 H1812s available; he might still have one.

I finished repairing both my Battlezone boardsets, but have a problem with the monitor with both boards. When you turn the game on cold,
everything is fine. As the game warms up, the monitor picture expands until the radar/high scores off the screen. I'm not sure if it expands side
to side, but I haven't really noticed it doing that.
 
Haven't worked on Vector monitors before, but I was thinking a cap kit... until I looked and saw there were very few caps. Can anyone point me
to something to try? Is there a common fix for this problem? It's the last repair I have to do to this machine and would love to get it out of the
way soon.
 
Thanks,
