Anyone ever seen this? FYI: Completely rebuilt ARII and power block... Its been like this for a while and I've never bothered to fix it... I did replace the TL082s for the heck of it and no change...

What does the BIP test look like?
Does the problem follow when decreasing vertical size?
I've never personally seen this issue before. Have you tried using the pot on the deflection board instead of on the video PCB board?
Have you measured the HV? What's the explosion of the Death Star look like?
The adjustments I speak of are on the SW VIDEO PCB board not the monitor itself.
You have to realize there are so many adjustments on the that can be made - it's really about finding the happy medium. You need to set it on the BIP test and get that set first. Then you'll find that you need to get the blue dots in the corners about 1/4" away from the corners. Typically you'll also find that by adjust one thing the graphics will become elongated (this the effect in the above photo). This damn board set is like converging a monitor - it takes time to tweak it just right.
Without a doubt this is an adjustment that can be fixed by using the POTS on the SW Video PCB.

Yeah, yeah, BIP test first.
If the boxes are unaligned in the BIP test, all else is lost.
