Zenith Hybrid Low HV

Update: I swapped out the 2 VDRs with MOVs, one at a time, and then both at same time, and there was no difference in terms of current regulation. At 18KV, current drifts about 20-30 mA as the set runs. Any setting of HV above 18KV creates excessive current.

I read in another thread that "Check the screen voltage on the HOT, if its high its an overload(bad flyback, shorted rectifier, cap, damper)." The screen voltage was high on the HO (measure 190-200v and should be 172)

I'm now wondering if the issue may be in the focus divider, as the tripler appears to be OK.
