repair shop for FM Acoustics

Looking for recommended repair shop for FM Acoustics trusty old 600A amplifier is dead on one channel...and I do not want to send it all the way to EU yet....Any recommendations are appreciated...
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!
I am in New Jersey if this helps you. I am familiar with the FM designs.

Happy Listening.
