Here and there when I can't find the type I need I just stick 2-6 R5000F 5KV PIV 200mA diodes in series solder an octal pin to one end and a tube plate cap to the other end and stick that in the TV...Seems to work about as well as a tube in many applications....In some cases (cough color TV focus rects cough) better.

R5000F is an old part #, not made anymore :/
now it's R5000F-T
Do they really hold up as a HV rect in a color set?
