Adjusting the vertical height and linearity controls won't help; all that would do would be to push the black "letterbox" bars behind the CRT mask, but you would still have the same 16:9 image on a 45+-year-old 4:3 tube. Replacing the capacitors in the vertical deflection circuits is a good idea in a TV of this vintage (looks like early to mid sixties), but again, if the video signal being fed to the CRT is 16:9 aspect ratio, it will not fill the screen--even if the vertical circuits are at their peak.

More like under-scan. Its there with an unoccupied channel of static tuned, and I have not seen the characteristic double image of foldover on it.
I've got a handful of brighteners too, but I tend to refrain from installing them unless the screen is too dim for viewing in normal night time room lighting.
