Have several CTC169 sets with intermittant vertical problems, (intermittant fluttering/colapse) Have checked the capactiors and connections following schematic no effect get worse when warm- tap sensitive in generalized way. Can desensitize (at least as a temporay test measure) by placing shims under board to deflect board upward. since hese sets use a moldulated flyback drive to run the vertilcal. I have seen several tips on vertical problems to replace the flyback. Any one have any historys on how often it is necessary to replace the flyback in ctc 169's to cure a vertical problem...
