Just like you used to test 9V batteries when you were a kid. ;-)
(Disclaimer, anyone who thinks I was serious... actually, go ahead.
If this doesn't get you, something else WILL.)
If you don't have an HV probe, the easiest thing to do is check the video B+.
It will be proportional to the HV. It will also be <200VDC, so your meter
should go that high with no problem.

Well, as the Midway cpu service manual actually says, just take two asperin,
the schematics, and...

Easy is relative. We'll wait for the next post to speculate.
Also, you haven't really mentioned what monitor we're talking about,
so advise is all abstract.
