am stereo ALERT

a Marantz SR-940 that I've owned since new (Jan 1986). These receivers were manufacturedfrom 1984 to 1987 using the Motorola MC13020 C-Quam AM Stereo decoder chip. Note that the similar Marantz SR-440, SR-640, and SR-840 receiver modelswere designed for AM Stereo but were sold without the necessary AM Stereo decoder module installed. This module, called the "AMS40", could be purchased from a Marantz dealer in order to add true AM Stereo capability to these models. The SR-940 came in three colors: black, silver, and gold.
There are NO missing switches or knobs. It is working and complete. It also comes with two working RMC-40 remote controls, the original "Handbook of Instructions", and two gold Marantz warranty sheets. The only thing missing is the AM loop antenna. It has A and B switches for A channel and B channel speakers rated at 100w per channel.
The whole reason I purchased it was because it had the AM Stereo feature built-in. I remember listening to a local talk radio AM radio station at the time where they had the "liberals on the left" channel and the "conservatives on the right" channel. It really felt like I was sitting between to people on either side of me talking!
