HV is around 10kV. I'd rather see 11 or 12, but should be plenty to produce an image.
Sure enough after a lot of fiddling with the trap magnet, I got a raster.
I get occasional arcing. I think it's my temporary aluminum dag isn't making good ground contact.
I'm gonna let it run a while and see if any problems crop up. If not, I'll give that CRT a proper coating
