Can Anyone Suggest A Good Amp Repair Tech In Colorado or anywhere for a Muse 160 MK II

Hello everyone. I have a Muse 160 MK II amplifier that has given sterling service but is now overheating on one channel (no smell or distortion) and I have stopped using it immediately until it is serviced. It's probably a simple bias adjustment but I would like it fully serviced. Problem : I live in a very rural area in northern Colorado and have tried without any success to find someone who can and will service this amp. Can a member please suggest a service shop anywhere that will do a good servicing job on it. I don't want to change amps, I have been through a lot of them in my time (I'm 76) both in England and the USA and am perfectly happy with the Muse even after trying out many much more expensive amps. With my IMF TLS 80's the sound is just as I like it. 


Thanks in advance for your help.
