Two Way Hourglass Bends on My KCS47

What's different is the yoke. Let me explain. The cockeyed picture is with my restored chassis from the original dark wood TV transplanted to the blonde cabinet and the yoke on the CRT original to the maple set. After an afternoon monkeying around with its original yoke to straighten out the picture without success, I took it off. The set screw wing nut that allows you to rotate the yoke was cross threaded and you couldn't tighten it down and, the yoke didn't look too good. OK I thought, just take the yoke off the dark cabinet set and put it in the maple set so now. the restored chassis is paired to the yoke it powered in the dark TV. The picture in the original TV didn't have this problem so it probably is a positional issue but I don't know how movement in and out along the neck could cause this.

If the yoke is too far back the beam can be obstructed by the aperture of the electron gun. Also the positioning of the Ion trap can have some influence, since it also bends the electron beam. The trap should be adjusted for maximum brightness with the yoke all the way forward against the CRT bell housing.

Ok I’ll make sure that’s the case. Stand by
