Two Way Hourglass Bends on My KCS47

[Chris K]

I got it. The yoke in the maple TV from my restored TV giving me "the bends" is fine. The wing nut that holds it to the focus frame not only provides rotating the yoke when it's loosened but, the trapped nut on the yoke the wing "screw" threads into allows the yoke to travel forwards and backwards as well. The only way you can do this (because the yoke itself is in a housing and you can't get hands on it to push it closer to the CRT) is to loosen the nut and take a screwdriver and push the yoke forward and screw the wing nut tight while it's pushed. Then you need to check the yoke position on the bottom to be sure top and bottom are pushed forward equally. I think it's a bad design. If you need to rotate the yoke for an adjustment, you can't tell if the yoke has slipped back away from the CRT. You can't see it to check. Anyway, the picture fills the screen now with no bends. I'm eventually going to remove the entire housing and yoke to be sure everything is in the correct position. I only figured this out by working on the other yoke assembly that was originally in the strong CRT maple TV. On the bench it was easier to identify the potential problem. Thank you again Videokarmers!!!
