Grundig Stereo Concert-Boy 4000 transistor radio made in Germany circa 1968

NOTE: This radio was sold several years ago! This top of the line set from Grundig is still in working order, although the band switch mechanism is not working correctly, as you can see in the video (but it is still usable). This set was sold on everyone's favorite online auction site as I found near mint black version of this set and I don't need three of these monsters!
