RE: TECH: Battlezone 15" monitor question (G05-805)

It is between the two black rubber boots on the HV anode wire coming off
the HVT.
 
It is labeled D904 on the schematic, it is not shown on the PCB layout.

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,
