Loosen the lock down clamp from the rear of the yoke and push the whole thing forward to the bumper stops. There should be 3 wedges.. One on the top center and two on the bottom all spaced evenly. Once you do this, you will probably have to turn the yoke a tad to correct a tilted picture. But should fix your problem if the wedges haven't physically came unglued from the crt and moved.

Another way to do it would be to physically remove the top wedge and while pushing the yoke up from the bottom put the wedge deeper into the void there to sustain the yoke angle

This has fixed the bowing issue. I noticed that whatever adhesive was used previously to hold the wedges was not holding very well anymore. I will probably use some sort of RTV since I've noticed that seems to be what is used in other units I have gotten recently.

At this point, I'm trying to figure out if I can fix the issue in the corners. It is very noticeable that if any sort of text or high contrast images are displayed in the top and bottom left, the colors seem to be separated. According to the service manual, this can be adjusted with permalloy strips or probably whatever I can make that's similar enough.
