Here is a Fisher 500-TX AM/FM-stereo receiver with TUNE-O-MATIC automatic tuning. A Fisher flyer I have has this receiver available in 1968. This is a 65watt per channel at 8 ohms (RMS) rated receiver. This receiver however, needs a couple things to make it fully operational like a new power switch behind that dual-concentric Volume pot. Unfortunately it's missing a few letters on the face plate. I'll probably update the power supply caps while I'm at it.
