This TV not only has AM-FM simulcast on the AM-FM tuner; it has a decoder for stereo FM as well. Look at the function selector. There is a position plainly marked "FM Stereo." There is a possibility that position is just a switch for an optional FM multiplex decoder which plugs into the chassis, but if the console was made after 1961, the radio is more than likely factory equipped for reception of the then-new stereo FM stations, if the owner's area had them. My best guess is that most of the time, the radio stayed on AM since FM was relatively new in the '60s, with few mono, let alone stereo, stations to be found unless the owner was in or very near a large metropolitan area.
