Is there a way to test my 3NP4 CRT? My Sencore CR70 manual doesn't list settings for it.

The CRT is obviously good enough to make some sort of picture, but it's hard to judge its performance by looking at that tiny CRT face, and I can't view the full image at all, while the mirror is off for recoating.

The turnaround time for recoating is something like 30 days, so I'll try to make progress in other areas in the meantime. I hope to be able to address the horizontal issues by viewing scope forms and peeking in at the CRT face.
