Electrohome G07. Cap Kit installed. B+ 120V. All adjustments work well. The chassis has the curl mod done.
I did a tube swap and the monitor looks really good, except the convergence on the very top and bottom edges all the way across. Its actually worse in the middle of the edges and better in the corners. I swapped the yoke from the arcade monitor, and have tried for hours to get the convergence right. I can get the center perfect. I can get the lines that pass through the center perfect all the way out to the edges. The only problem is the horizontal lines away from the center wont allow the magenta to converge with the green. It seems like the green is too far out. There is no adjustment for this and I am wondering if the tube is not quite compatible with the yoke. The old tube had 19v90 stamped into the glass, but the new one has 20v90 stamped into it. It came from a 19" TV and the tube is exactly the same size as the old tube and the bolt spacing and fit was perfect.
I used the purity/convergence rings original to the TV tube that is swapped in. They were perfectly marked for position, and replaced exactly where they were from. I have adjusted them for hours and the middle converges perfectly.
I installed the yoke at a certain distance to get the purity right. Then I can rock it up/down or left/right to get the outer edges to converge. I can get the red/blue all over the screen to converge perfectly, but at the upper and lower edges, the green and magenta wont line up. Its reallly not that bad, but its noticeable to me...
I have tried convergence strips, and they work great in the corners, but dont quite get the magenta to move into the green line to fix my edge problem. I noticed another person on here had this problem, but it didnt seem resolved. If anyone has experience with this please let me know any possible solutions. Thank you very much.
