BeoLit 600 Colouradio (1974)

BeoLit Portable Radio

Production: 1974 - 12/1976

Designer: Jacob Jensen

Documents: Service Manual, Schematic

With the introduction of Beolit 600 in 1974, it also marked the end of this particular range of portable radios.  After Beolit 505 / 707 were taken off the market, it was going to be a long while to wait until the introduction of BeoSound 3 almost three decades later.

Slim and very modern in appearance the radio was easy to use and light to carry around. Internally, it held its source of battery power and was able to receive FM, LW and MW radio bands offering 1W of undistorted sound.

Tuning was by way of sliding a pointer along a scale on the top of the unit and AFC was provided for the FM waveband. The FM band covered 87-5 - 104MHz, MW 186-587 meters, and LW 857-2040 meters

There were connections for record deck/tape recorder and an external loudspeaker as well as an external power unit.

Shown below are some of the original design sketches made by Jacob Jensen of the Beolit 600 Coloradio.
