ZENITH 26kc20 QUESTION

[iong]

Need advice. Red gun only appears to be out of focus. When trying to converge my red gun on both crosshatch and dots only the red gun is bigger and thicker and overlaps top and botton of Horz lines and when using dots the red is a bigger less focused blotchy dot that surrounds the converged blue and green. My crt tests good and also I had another good crt in the set and has same problem. The color tracking is fine and when watching color show it's hard to tell. B/W look like red is badly out of convergence and Salt and pepper snow is pink. I need some direction cause I don't think this is a problem with the convergence but something wrong with the red drive. If I lower the contrast the red on the dot patterns becomes more focused. Please help.
