I haven't gotten to this one yet, but I will check the HV transistors and caps first. Has anyone else seen this before and does anyone have a schematic? Thanks for any assistance. JRW

Fixed FYI

I finally got to fixing this thing. The problem I found out is a semi-common one. Shorted HOT Q706 2SC5411 and Q710 SFS9634 replaced. Works like new.
