Yoke failure is generally more extreme than that. Also a low high voltage condition.
The picture shown looks rather good.

I dont think its the yoke, every one Ive seen keystoned was
very bad. Look for magnets missing from yoke or if its got
"wings" with magnets bend them a little. Dont think its the centering rings either. May be just the nature of the beast....

I kind of figured it probably wasn't a shorted yoke, but thanks for the replies. I'm going to do some more searching before I give up on perfect geometry.
