I've got it basically working. The one minor problem left is: after it is on, working good, for several minutes (sometimes as much as a half an hour) I start seeing the occasional horizontal black line going across the bottom 1/4 of the picture. This is accompanied by jittery (but it doesn't loose sync) vertical. (I've already recapped, changed that 5Y3 socket, realigned the audio IF, added vertical retrace blanking, and replaced most of the resistors which have anything to do with vertical output in the process of fixing a previous problem it had of not enough vert size) But I'm not sure if this could be caused by a vertical problem anyway, the way it seems to turn single horiz lines on the screen dark. Any thoughts?
