For your consideration, we have a working example of the Proton AC-420 CD Player. This rare unit is in excellent working condition, and good physical condition. Physically, the face plate is in very good condition, with only small blemishes. The top panel has some scratches, blemishes, and some rust marks. It is not dented, and the next owner could strip and refinish it if they desire. See pictures for further details on condition.
We don't have the original box for this unit, but we take packaging and shipping seriously. We spare no expense and use heavy duty boxes, several inches of polyethylene foam on all sides of the unit, and use water activated, fiber reinforced tape on all seams.
