This is a Vintage Early 1970's Eldon Power Crystal Radio, model F002-12. The unit is complete with all its circuitry, and parts. I haven't worked on it so I cannot verify it as working, and will sell it "as is." The tuner, diode, and everything is there, and in good shape. I believe with a little attention it can be working. It is a nice historical crystal radio, and a great addition to any collection. There is no instructions, but an earphone is included.
