all the equipment ( meter, scope, variac, DC power supply ) also
knowledge & patience.
The power supply, horz osc & HV all have to be working or you get
"dead set". There is also a one chance kick start for the horz osc.
to spice things up !
If you look at it & dont hear the quick degauss hum at cold turn on
it may be just the main fuse. ( 7 A fast blow)

Well i don't like weird power supply circuits and it sounds like a bit of work just to find out if the crt is worn out. i haven't justified the expense of a crt test/rejuvenator yet,so i think i'm going to pass on this one. Thanks everyone! it is in Hendersonville tn about 10 miles northeast of Nashville if anyone else is interested.
