Convergence ?

Don't forget the shadow mask also plays a factor.

? I didn't think the mask affects convergence, only purity. ?

It affects both. Minor warpage or magnetism will affect purity, severe warpage affects convergence and purity, but these tubes were very stout physically and it would take a significant impact to warp the shadow mask bad enough to affect convergence.

Later tubes were more prone from bumping, and just looking at a Trinitron crosseyed would give them fits.

Besides Trinitron, I had a Samsung 32" widescreen that lost purity with a little impact... ouch... very sensitive it seems
