Many newer florescent lights have switch mode supplies that jam everything... many switch mode supplies jam everything (I can't use power inverters to demonstrate radios at swapmeets because they jam the whole AM band).
McDonald's is so bad a number of AM and FM stations die when I get my car radio within 20' of their building.

Well the place where I work isn't metal or brick, its a regular old stick built building that part of it dates back to the 1920s (that part is cement block) but then the rest of it is a timber frame building that was built in the style of an Amish Barn.
There are Florescent Lights throughout the building but as far as I know none of them are new enough to have electronic ballasts in them (the newest florescent lights in the building dates to the mid 1990s).
They do have a security system but like I said it only affects the FM Band, and not the AM Band because when I drive up to the building it knocks out my FM Band on my car radio but the AM Band on my car Radio isn't affected.
As for trying to repair the broken 1st IF Secondary Transformer, how does one go about doing that? Can one use a modern IF Transformer from a more modern transistor radio on this radio?
