i do have an interesting 16GP4 that reads way high on the emissions and cutoff is good but to get a decent image it needs a brightner and the ion trap has to be pushed as far forward as possible , its touching the focus magnet , my only guess here is that it was rebuilt but not properly.

It might have been rebuilt with a straight gun. Remove the ion trap and see how it works.
