That is wierd, because red and green are supposed to move at plus or minus 120 degrees, and this pattern shows red displaced straight down on the far left. Red is displaced a normal way (down-left) at left center. But it appears that if you fix the left center, the far left will be displaced inward. Red in the lower-center-right has a direct inward displacement. I'm now thinking this could be deflection yoke design or winding tolerance. Purity looks good, so the yoke is not in the wrong position.
It makes me wonder if the yoke from a good CTC-5 can be subbed electrically, just to see what happens electro-optically.
Good luck!
