HI; Looking for the vertical sweep board for a 1958 Sears Silvertone set Chassis # 528-51184/Model-8186. Having problems in K-3 K-4.thanks chip

Well !!! I found the problem with my source voltages. Located on the vertical sweep board, pin 6 the 225v connection on the CRT was touching the - negative side cap C-5 of the 230v source. Having corrected this NOW all my voltages seem to be in line. I do now have ARC at the top of 1B3, but not enough voltage to lite the tube or get a reading off my probe. This voltage is only accomplished after I touch with my--- METER-- C-41 a .01 cap that is between B-1 the horiz wave form and L-14 the Horiz hold adjustment. Any help you guy's could give me would be greatly appreciated. chip
