Tube swaps: Different neck lengths and room for convergence rings
I did my first tube swap the other day and it came out great. I used a tube from a Magnavox TV and replaced a Roadblasters burned K7901's tube. I swapped the yoke, and although I couldn't get the convergence 100% perfect, it is close enough that I consider it a complete success.
Today I tried to do a G07, and it was a complete failure. The thing I discovered was that there was not enough room to put the rings where they are supposed to go, because the G07 yoke took up too much space. At first I thought the G07 yoke was longer than the TV yoke, but then I discovered the neck on the TV tube was actually shorter. Looking at the tubes I've pulled out of TVs, there seems to be varying lengths in the necks, and the rings are positioned at different distances from the yoke. A lot of them even have the rings as part of the yoke.
I was wondering if anyone has found a way to use these shorter neck tubes successfully? I was wondering if I could modify the G07 yoke to make room for the rings, by cutting off part of the clamp section. I'd hate to ruin a G07 yoke if it didn't work though.
I know there are differences in gun alignment and there can be incompatibilities when swapping tubes, but I am wondering how much of these problems are really caused by not being able to position the rings properly after swapping yokes?
