Using old television tubes for Arcade games?

I haven't had good luck changing out width caps on K7000s. It affects the linearity as well as the width, and there is adjustment for linearity. So you can get it to fill the screen, but it looks like crap.

Better to swap yokes or keep looking until you find a donor with a closer match.
