 I am not a repair tech and the onlty thing I can fix is a sandwich.
 I have a Marantz 120 Tuner and the FM doesn't work.
 The repair shop said the FM mute transistors are bad and they can't find any new ones.
 Does anyone know what the repairman is talking about and where those parts can be found?

You might give Tom Williams a call about your needs. He restored/rebuilt two of my vintage Marantz receivers a couple of years ago. He is very knowledgeable and great guy to deal with. 

I believe I'm his only customer from Hawaii.

 Thanks for the info.
 I emailed Mr. Williams and I'll see what he says.
