repair shop for FM Acoustics

you might be SOL here Prcinka in that you might have to ship it back to FM Ac in CH.
There used to be & maybe still is an FM Acoustics dealer in Co Springs (I've met the person & been to his house to listen to some FM Acoutics gear a couple yrs back. Nice fellow).
I believe the business name is Audio Limits - it'd a father-son team. here is their website (several preowned FM Acoustics units for sale):

good luck!

OK. Thanks Bombaywalla...

I am in New Jersey if this helps you. I am familiar with the FM designs.

Happy Listening.

Excellent! Please check I have sent private message to you.

Audio Limits no longer is a dealer for FM Acoustics.
