benman, I suspect you are right, although there WAS those two
arcing events that I can't prove were not in the tube.
I surely have less than 200 hours on it probably more like 100.
And it was never run for more than a few seconds at a time
with the red gun drawing grid current more than 10% of the time,
as when actually watching I always set it well below the "knee" where
the color rendition gets poor.
I suspect the arcng events.
Its not the resistor chain: rock stable for an hour.
I also vaguely remember asking McVoy about the red screen.
I seem to remember "just run it all the way up and don't worry".
Also ... my camera shows that the brightness limit for true
color accuracy has not dropped more than 1/2 f-stop (i.e. to 70%).
