HO 10 Monitor Scope Trouble

[Charles W. Morehouse]

Ron,
I suspect that one of the HV caps is arching. Have had one do that before.
Suggest that you replace them with two .05 @ 1600v orangdrops in parallel form
Antique electronics. Also replace all the resistors in the HV circuit. Check
that 1V2 also. Luck and 73's.
