I had a few minutes to spare last night so I looked at the horizontal centering. I tried putting a 100uf cap across the control to see if it made a difference and it did nothing. The pot reads at 10ohms and smooth from end to end. There is ~ +385VDC or so on the input, wiper, and output of the control. I'm not quite sure where to look next.
