I did find several changes made in the zenith color service manual talking about revisions to the HV regulation. Some had a 6.8meg resistor across the varisistor, and a change in a 1 meg to 2.0-2.4 meg resistor off the HV pot, part of which sets the voltage divider range.
The easy thing would be to 6.8meg across the VDR, esp since I could do it from the top fo the chassis on the exposed term strip.
the regulation is working but its range is very narrow (all most all CCW) again this may be due to the use of a non factory orig VDR (the only one I could find that the supplier said was a correct cross).
