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?

When I shrink the picture (using controls on the PCB) the problem goes away...

Its a WG6100 ... so no adjustments on the deflection PCB...
 
Have you measured the HV? What's the explosion of the Death Star look like?

I've not measured the HV but the Death Star explosion looks pretty good... pretty typical WG and kind of stresses the monitor a bit but all of the concentric circles are fine.

also on the grid test it looks like this... pretty strange huh? it appears to be unable to complete the horizontal lines... and each color is the same as well.

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 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.

Got it ... yeah I've tweaked the crap out of it... when I bring the picture into the point where it looks good... its too darn small... and looks like crap... if I stretch it out it seems to break on the ends...

I was a bit confused by what you said here... it looked like you referenced some pot on the deflection (which I interpreted as a monitor adjustment) instead of the AVG board itself...
 
Yeah, yeah, BIP test first.

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

I don't have a pic of the bip test on me... however they are aligned just fine... here is the cross hatch pattern...

I will redo the bip alignment just to be sure but I'm pretty sure I've already exhausted that...
