BeoGram 4001

BeoGram Record Decks

Production: 1977 - 06/1980

Designer: Jacob Jensen

A prototype model of an all-black Beogram 4002, this deck never actually made it to the salesrooms. The only real difference to the record deck as compared to the original Beogram 4002 was that it was fitted with a DC motor, rather than a standard AC unit.
