National Panasonic RS-4150

The RS-4150 (also called the Stereo Mac ST-3) was a boombox sold by Panasonic, probably during the late 1970's. It does not appear very often within the collector community, but there were at least two versions: The black RS-4150LJ, and the silver RS-4150FD or RS-4150T. It has both Line In and Line Out. On the upper left corner is a clip for an optional microphone.
