I am attempting to locate a part for the 725 I am repairing. It is a 100uh IF coil (transformer). Its old part number was LAL 03NA 101K, but that number is now used to ID another type of inductor so it is a dead end. Does anyone know who used to provide these coils to ICOM in the 80's? If they are out of business (likely), does anyone know who makes these kind of coils now?

Toko used to make these coils. It looks they have been acquired by Murata. Many of the old parts were abandoned at the time the electronics industry embraced the "no lead" initiative. They just abandoned the old stuff and created new parts that met the "no lead" criteria--no attempt at compatibility with the old.

There are a few people who have been successful in repairing, rather than replacing parts like that.
