Got the monitor reassembled last night.
Fired it up from a cold start, and the problem manifested itself right then.
Cycled the power off then on twice, before the raster image would stay on.
Monitor worked for a couple of hours. I went to bed.
Next day, turned the monitor on, got a few minutes' use and there was an
audible 'snap' sound and the zoom/defocus/fade to black event recurred.
Powered off and on, but problem would just repeat.
Wait 20 minutes, and powered it back on. It stayed on for as long as I was
using it.

The problem is very much intermittent and does not seem to be related to
temperature as I had first thought.

I did throroughly clean everything remotely related to high voltage. In
fact, the monitor was clean to begin with, but now it's as clean as when it
came off the assembly line. I just wish I had a schematic so I could better
pinpoint the problem. I'll bet it's one component that's causing this. Would
be a shame to scrap such a great tube just because of a possible capacitor
or flyback problem.

A friend suggested I get an LCD, but I can't find one in the 21" range with
a native 2048x1536 resolution, much less one in the $500 price range.
Working with a monitor that you don't know how long before it decides to
shut off is really frustrating.
