I guess I didn't describe it very well.
what I'm seeing on the screen is pretty much bilateral, it just was not noticed until the width was drastically lowered, wider in the center and more narrow on the very edges.
Which may be caused by 1 or more of 2 things I have yet to try and adjust.
Horizontal linearity and horizontal drive.

Horizontal lock / frequency / hold seems to be right where they need to be, no issue there.
Horizontal drive, adjust CW as far as pos w/o presence of vert white line or compression in center.
Too far CCW perhaps? Could that do it?
Or, Horizontal linearity just needs to be touched up as well, as mentioned, the coil B4 is not as easy to reach as the width and drive adjustments are, but there IS a hole in the back cover to stick a tool into the HV cage to adjust horizontal linearity, which I will try this weekend as I'm tending to think it's that adjustment over the drive, although it may be both, not sure.
