The only problem left is that it's always had a small color problem where the outline of bright objects, like red and green, have a magenta outline to the left. Here's a photo of a bright red object. Looks like red starts a little late drawing from left to right. Is this convergence?



This doesn't occur on the old TV, which is the same TV as this one but with a tired tube.

The differences in C1, C2, and C3 had to be compensating for the old tube's cutoff values. Setting them to equal default values with good results indicates that the new tube's guns are much more balanced.
Are you suggesting the tube was replaced at some point?
