"This item is a DIY Analog Synthesizer Complex Sound Generator with power cord. It also contains a 9v battery inside the case (you have to unscrew the 4 small screws on the bottom plate. It has a speaker as well as an output jack that allows you to push the sound to other audio devices.
I believe this device is either an old Telstar kit or even possibly is a total custom job based the chip schematics. The estate this came from was a true "old school" electrical engineer; a magician."
