I moved the balancing capacitor from its original position to the hot side of the yoke. I didn't take any before pictures because the ringing was so severe I was afraid it might damage something.
I haven't aligned the horizontal section or do any serious adjustment of the vertical. I was mainly interested in seeing whether the ringing would be reduced and if the focus would be good. The focus looks good, there is still a little bit of ringing.
The balancing cap in the original yoke was 47pf and the one in the RAM replacement is 68pf. I'll probably use a variable cap first to see what value works best.
Then I need to shim the yoke. For some reason it tilts down a little when it's mounted in the saddle.
Then I'll align the horizontal. That will take care of the curvature and reduce the flagging. There was always some flagging unless I was receiving an over the air broadcast. No chance of that now. There may be a minor problem in the sync separator.
