Back to working on the IF coils. I got an IF coil that has a smaller diameter coil that the one I tried first. Must be out of a late 30s early 40s set since the rubber it crumbling. It has a bakelite frame holding the trimmers and the coils. The replacement is on the left, the original on the right:

I was able to separate the coils from the trimmers by cutting it with a hacksaw:

Unfortunately the bakelite did not respond well to drilling. I was trying to drill a hole to mount it onto the original trimmer frame.

Some plastic tubing and liberal use of epoxy and I was able to get the coils mounted to the original trimmer framework.... MacGyver would be proud.

The coil wires and new lead wires were soldered to the trimmer lugs and the whole thing fit nicely into the original can...

Here it is fully mounted onto the chassis:

...and a final view of the restored underside of the chassis:

Its playing nicely now and has yet to be aligned so may be even better. Next time... more on the cabinet
