I have also attached a couple more pictures of the set issues in operation. Most of the time when I can get color it doesn't lock in, more of a rainbow. Playing with the horizontal hold or fine tuning sometimes gets the chroma to sync properly.

I have done an experiment where I pull the chroma oscillator tube out during operation, let the tube cool down, and then put it back while the set is on. While the tube is warming up there is a point for a few second where the chroma locks in. However, after the tube is fully warmed up it becomes a rainbow again.

Also, having a little bit of trouble with horizontal sync in general as the vertical lines in the cross hatch are difficult to adjust to be straight.

That's the one. I see the other that gives trouble has already been replaced. Also the peaking coil has been jumpered out. Try to replace it if possible.
