Nice catch! I meant 19AP4. And, yes, I completely forgot about the trap magnet
You get spoiled using the little test CRTs which don't need them.
After adding the ion trap magnet and a whole lot of tweaking to it, the centering magnets, focus coil, etc. I got these images. The brightness is cranked all the way up and the hor. drive adjusted for the least noticeable dark bar on the left. Too bad Sams doesn't include any directions for adjusting the controls.
It's a little disconcerting feeling all my arm hairs tingle when I reach for a control
