So I've been playing a bit more with the Onyx today. Convergence drift is definitely an issue, however I have a new problem now, and this is on the green tube only. At first I thought it might be a warmup thing I just didn't notice as after about an hour it was gone, but it came back a little later again. Technically what happens is every hard vertical line gets a 'mirror double' a tiny bit to the right of it (right on the screen, so that's left on tubeface I think?), which makes it look like my convergence is way out of whack too, but it is only this phenomenon on the green tube giving that illusion.

These are the same section of the screen on the three different tubes (don't mind the lack of focus, you can see the problem on the green clearly):
Here it is with an actual icon on the desktop:
Ignore the diagonal stuff, that is just the iPhone's camera artifact.
I also have what I believe is called ringing on the left side of the screen, though it was pretty mild, yet on the green tube it seems to have doubled at this point. If I only have the red tube on, I can't really see any ringing, and if I turn only the green tube off, picture is near perfect. On the blue tube, ringing is strange, as it only appears in the form of a single vertical line that is a little brighter than the rest of the image?
I hope replacing the old caps will fix this (?). Is there a source for those weird capacitors that have one center leg and three outer legs in a circle? Or will I have to jam in regular two legged caps?
The thing is, this phenomenon appeared for the first time today, it went completel invisible at one point, then came back even worse than this. I just turned the set back on real quick to snap a few pics for you guys.
I actually had this problem on a CRT monitor a while ago, although there there were multiple copies of vertical lines, each a little fainter than the rest, and I never could find out what it was. It also came and went when it pleased. So if anyone has some pointers, I'd really appreciate it.
