Wayne, I had the same issue with linearity affecting convergence. The capacitors throughout the vertical sweep circuit had been replaced but could I still could not get it right. Further investigation I found some of the resistors drifted and testing each of the capacitors I had replaced I found some of the new replacements were out of tolerance.
Fixing the linearity helped considerably with convergence. Going over it again and again and again I finally got it right.
