getting there, I brought it in the shop, put the chassis back in and started setting it up (I had swapped in a replacement CRT, so I knew it would require a full setup)

In the process of adj the yoke for level I got bit pretty good. seems the outside of the CRT cover is not grounded very well. Perhaps thats just the way it is with these 21AXP22. I will confirm that all my grounding straps are in place on the CRT cover hold down AND the connection the the chassis is good. From what I can see the only connection to the chassis is a pressure connection from tabs on the front of the CRT mount that press into the chassis on the front.

I had a heck of a green neck shadow that I could not seem to correct without upsetting the purity. I never got the purity perfect anyway, I could get the red blob right in the cener with nice blue and green blobs around it, but when I moved the yoke forward I could not get a pure red screen, the bottom was the problem. I have not yet futz with the screen magnets nor tried degaussing (My 1st 21AXP22 set) so I will have to figure out how to adj the perimeter magnets so they are retracted and give it a proper degausse. This set is def a bit trickier than the later roundies I have worked on.

I need to get a handle on this hot yoke first. I did not try and measure it but the metal plate is def sparking up when grounded.
