Swapped CRT and a ?

[jr_tech]

Sometimes a re-builder would notice an aluminized screen and rebuild the tube with a straight gun rather than a bent one. They would usually put a note in the box stating that the ion trap magnet should not be installed on the rebuilt CRT. My guess is that you have a 21XP4-A (Aluminized) that has been rebuilt with a straight gun.

That makes sense, but I'm puzzled by the fact that he still has a raster with the ion trap installed.

This is a pretty good puzzle... hopefully a picture of the gun will reveal if it is bent or straight.
