K7000 loses vertical synch when focus pot is adjusted
Heres a wierd one, Seems like some kind of power supply problem,like the draw from the focus grid is dragging the VHold down.... I recapped, replaced flyback, HOT, VR and Retrace cap.. The picture is fine and stable if its out of focus..When I adjust the focus, I get jittery vertical hold..its looses it, then snaps back every second or so. If I move it back to unfocused, its fine.. I havent tried a different tube though.. Anyone seen this?
