lack of horz sweep on color roundie

this ties into my old thread about a purple edge on my roundie, which was related to a lack of horz sweep (I think). I may have found something. while reviewing some other schematics I decided to put a 78pf cap across the horz windings (there is one internal to the yoke). This increased the sweep about 1/2 an inch, enough to get rid of the purple edge and make the horz centering less critical.

Now I dont know if the internal cap in the yoke has just opened up or what, but at least I am getting somewhere with more width.

My plan was to pull the yoke and just replace the existing cap and see if thaty does it.
