BeoLit 500 (1972)

BeoLit Portable Radio

Production: 1972 - 12/1975

Designer: Jacob Jensen

Following on from the Beolit 400, the Beolit 500 too offered FM reception only. However, this particular portable radio also contained its internal transformer making the BeoPower unit no longer necessary.  One could plug the radio into the mains socket to use it. It offered a full 1 watt of undistorted sound.

Function-wise, the radio included a two-position tone switch located at the side of its AFC switch which ‘chopped off’ the upper frequencies of FM broadcasts.

Not too popular a model, the portable radio was replaced by Beolit 505.
