I hear you regarding diddling the IF transformers. I ruined an off the street Emerson version of an RCA CTC7 trying to diddle out the worms in the picture. The set was hooked up to cable, without a converter. It did not dawn on me that Analog TVs back then were not designed to receive adjacent channels. Other than Channel 4 and 5 where there was sufficient space, no geographic area had adjacent stations, such as having active stations on Channels 2,3, 4, 5, 6, etc. TVs back then did not have the ability to tune sufficiently sharply to reject the adjacent channels.
