I tried the coil with both the 4.7pf and the 33pf, and it worked better with the 33s, so I went with them. Sound is pretty good now, so I'm back to the horizontal.
As the set warms up, the horizontal loses sync several times. The horiz hold control is very touchy. The slightest movement of the slug causes a huge shift in the pic, and the lock range is very small.
Could this be caused by too much pic width? Here is why I am asking this. My set uses a width sleeve inside the yoke. When I started on this set, I found a piece of metallic tape inside the yoke for a width sleeve. Don't think it was original, and it was crumpled after I separated the yoke from the CRT. My CRT is one that stays in the cabinet, so I am using a test CRT. See pic for what was in my set vs the sleeve I am trying. New sleeve is wider.
I couldn't get that piece of tape back in the yoke properly, so I've been restoring the set with no sleeve meaning maxed width. Yesterday, I checked in my junk box and found a yoke with a width sleeve, so I tried that.
I could see a reduction in the width, but after a minute I heard some arching in the yoke, and I lost HV. Pulled out the new sleeve, and HV was restored. I thought maybe there is a bare spot on one of the yoke windings, so I have coated the windings with Corona dope and am waiting for it to cure.
I also replaced the horiz output tube, and no change.
