Congratulations!
I just went back and looked at the picture in the other thread. A fine looking set.
The Abbott link didnt work for me at all. You can't go by the color in the brochures, though. I have the carcass of an "Atherton", and it's brown or dark red or something. The one in the brochure looks really blonde. Isn't the power/volume the center of the concentric thing below the channel knob?
Are these the reddish brown capacitors the "Good-All" ones? Someone over on the TekScopes list led me to believe these are a lot more reliable than black beauties. I guess that doesnt say a lot.

I got the impression they're not all bad. I don't know if theyre paper. I guess they could have plastic in-between the foil like an orange drop.
I think the x-ray thing happens when you have no HV regulation. You would also have an unwatchable picture....
Red is driven the hardest on all (almost all?) color sets of this period. It's just a smaller difference on sets with the brighter (orange?) phosphor. Apparently there were some tubes where the red phosphor was strong enough that the green was actually the weakest. I have never seen one. If this happens on a set with only 2 drive controls, you have to swap the red and green cathode leads to get it to track.
Is your 21cyp22 actually an A?
