This Magnavox 8-track recorder / player was originally designed as a drop-in accessory for Magnavox stereo consoles, but is a stand alone unit as well, with a built-in 120 volt power supply / line cord.. The output and input cables are attached, and terminated with RCA plugs. I believe this unit is functional, but as I have no way to test it, I'm listing it as parts / repair only.
