An additional thing you can do once you have all horizontal adjustments optimized and bad components identified and replaced is swap the HV rectifier and or focus rectifier tubes for solid state substitutes...The SS parts don't have heaters and reduce the flyback loading a few watts which can be helpful in cases like this.

I put in SS tubes for the focus rectifier and HV rectifier before I even fired the thing up. Too nervous about flyback issues. As for the HV, that was the "sweet spot" for the HOT current. It goes low at that point and then goes back up by a few mA. Schematic calls for HOT of 160mA on the SAMS. I'm pulling 30-40mA above that. I will say, after replacing that 66meg, my HV is a little low around 23kV at full adjustment. Adjustment calls for 23.5kV. I may repeat the whole adjustment process again for the HV.

Also, when you get to the point of considering alignment, don't do it until you see how much improvement you can get just by fine tuning.

Width is just how the player decides to play that specific video. Not sure why, probably formatted like that. It was converged with a full-width image. I'll try to fix the flyback issue first. I'll start probing around.
