Sadly, the tv's rings in their original position didn't yield a converged image (don't know if the tv was poorly converged or if it has something to do with the tube swap, and yes, I marked the position of all the rings). So I've had to resort to the frustration known as convergence.
I've gotten the red/blue convergence pretty dialed in as you can see from the first pic (except the upper and lower right corners, but I imagine my magnetic strips will rectify that). However, the green on magenta convergence isn't going so well thus far. Converged in the center of the screen, but the entire top and bottom are out significantly. It seems odd to me that the whole center horizontal "band" is converged and the top and bottom "bands" are not.
I did a little searching and came across this post from the ever helpful modessitt in which he said sliding the rings forward or backward can help with convergence. That's what I plan to try next. But in the meantime I thought I'd throw my issue out there for any feedback. I have 2 questions.
First, obviously, is why am I having this trouble with the green and how do I solve it?
Second, what is the right spot to (theoretically) place the set of rings when sliding it onto the tube? The tv tube's rings were positioned quite a bit closer to the neck board than the arcade tube's rings. Looking at the 4600 manual, it appears that the tv tube's rings were placed in the wrong spot (but maybe it varies from tube to tube???). OTOH, if I place them in the spot that appears to be right (from the standpoint of this noob), there is very little room to move the yoke back to do the purity adjustment (centering the magenta band). So let's say you were handed a tube in one hand, and the rings in another. Where would you place the rings?
