... It's a phonograph and stereo in one, all parts are contained within the cabinet. I'm interested in any history and whether or not it is worth anything. It's in good working condition.
This was a high end unit. With the optional FM tuner, $365 equates to about $3600 today. Magnavox service information usually goes by the numbers stamped on the chassis because they used the same electronics in many different cabinets.
These sets were the last of the 78-rpm only phonographs. The LP came out in '48, the 45-rpm record in '49 and by '50 most sets had 3-speed phonographs. Many owners of these expensive sets had the original 78-rpm record changer replaced with a 3-speed changer.

You use the word "Stereo" in place of the word "Radio". This monaural unit was built over a decade before stereo sound became available. However it is a wide-band AM and short-wave receiver considered high fidelity in its day. The "Sharp Tune" position on the treble switch was used to tune in the station with the green tuning indicator tube in the center of the dial and then the treble switch is returned to full range position for the best sound quality.
Some eBay and junk store sellers that are unfamiliar with this equipment hear it crackle out static, noise and hum will proclaim that it works perfectly.
It is over a half century old so unless it has had some serious work done, it probably has only a fraction of its former performance. "Good working condition" means that it sounds very clear, clean and powerful with rich bass that you can feel. The controls all move silently without any noise or distortion, the green tuning indicator shines brightly, the dial sparkles and glows nicely in the dark. You can stack ten 12-inch records on the 78-rpm automatic record changer and have it play bouncy swing music from the '40s that's a pleasure to listen to.
These haven't become very valuable yet. They take up too much space for just a knick-knack, conversation piece, collectable item.
Here is a '47 Magnavox Regency Symphony that I picked up for $20 over 20 years ago. It's a step up from the provincial with twin speakers, twice as much audio power output and two additional station presets. It originally cost $475 without the optional FM tuner in '47.
