The HV was measured with G2s turned down, dark screen and HV was still 27 kV. 6LR6 cathode current was 190-215 mA, should be 160.
There was a 6.8 Meg 5% resistor off the HV pot that measures 7.3 M, and changing it to a pair of selected 1-watters brought it down to 6.6 M. (I had tried a 5.6 M and that dropped HV to 12kV) Now the HV is 25 kV at the low end. the cathode current dropped to 160 mA - a bunch of baby steps just getting here!
During scene changes with DTV box signal, it ranges 23-25 kV which is acceptable.

Now the only thing keeping it from the final set-up is the vertical issue I was ignoring. The V-hold pot is at minimum and frequency is still too low, the frame jumps up a few times depending on video level. Adjusting the height and linearity works as intended, but adjusting any of the V-controls causes a momentary loss of vertical sweep. Not acceptable at all. First, I will check resistors AND then replace just the loop capacitors.
