I've understand that the ION Magnet should be adjusted to the brightest image. I backed mine off slightly from maximum brightness to eliminate shadows on the edge of the picture tube. I assume this is OK considering that the ions still will not hit the phosphorous because the electron gun shoots out deflected?
Then I have heard that if you don't adjust the ION magnet just right, it will mark the center of the picture tube.
