Turntable repair Denver area..PLEASE HELP COLORADO

Hello all,

I hope some of my Colorado folks know of a good turntable expert in the area. I have an original Michell Gyrodec which has been the source of many headaches. I had a cartridge and tonearm wires replaced at my local shop (not in Denver) and it sounded good for a while. I am now missing one channel and me thinks the tonearm wires have come loose. I need someone who’s been doing this for a while and might know a thing or two about vintage turntables and arms ( the arm is a Zeta from the ‘80’s). 
 

Hoping to find a guru in the Denver area who can help me love this back to brilliance.

Thanks in Advance
