I removed the anode going into the HV Splitter from the Flyback and turned
the set on, the set draws normal high current but I still notice a pulsing
(on/off) of current from my Variac. Seems something besides the HV splitter
maybe cause here since I completely removed the HV input from the splitter
and I still have a Pulsing on/off slight surge (about the normal current
draw) on my Variac)
