Zenith 9S232 sensitivity control
#6

My chassis had the antenna coil inside a can on the chassis. I was lucky enough to find only one end broken on the primary. I scraped enough enamel off and soldered an extension on it. Then hot melt glue to hold in place.

I think your coil pictured is #14 the RF choke. These are notorious for being broken or eaten by mice. They will cause similar issues like you described. B+ is supplied to the RF amp plate through it. It’s very likely you have no plate voltage. Someone might have a better idea how critical it is, but with multiple taps I suspect it’s important.

I’ll look in my shed on my junker 1204 chassis.
