Hmmm Jeff,
Is it jealousy...or PMS?
IMHO a CRT can be diagnosed 99.9% of the time with voltage measurements and
a 10K/10Watt
resistor! This is one of those 0.1% that's inconclusive.
Perhaps the difference is that we use and understand technical measurements
rather than rely on a piece of equipment that you always seem to need a new
socket for. To answer your question, yes, I have one. (but I'm not sure
where).
Hope you feel better soon ;-)
