It's like the beams from the guns are somehow too large, causing a strange pattern on the screen. It's wierd though, I can almost actually get good convergence.

All the screen and background controls work as advertised, but all the guns will cause the same pattern to appear on the screen when advanced one at a time. Looks like tri-color chicken pox or something. Also, no amount of messing with the purity rings, blue lateral, or yoke will affect it.

Please tell me the mask is not bent...
After looking at your photos with Photoshop, I removed all of the red, green, and blue blotches. What was left was a framework of nice, crisp vertical and horizontal lines, delineating what would normally be a color bar test pattern. This, plus your previous observations, demonstrates that everything from the yoke to the AC plug is working correctly. I'm sorry to say, your problem involves the shaddow mask assembly.
