Mc Mx 132 AM cable

Does anyone know if mcintosh still sells the cable to hook up the AM external ant.

Yes contact their parts department. Also you can get one at, they may have a used one.
i bought a used mx132 from audio classics a few years ago. after writing to them and asking questions they mailed me 1 for free. now that's what i call "customer service" i also bought 2 mc602's from them around 6 years ago!
