Beautiful Beomaster 900K in a beautiful Brazilian rosewood cabinet. Fully checked, power capacitor renewed and lights replaced. Clear and hum-free sound.

To ship this product properly it will of course be expertly and carefully packed with protective material in a strong box.

The inspiration for the Beomaster 900 came from the spirit of Henning Moldenhawer.

The first product of this new era was launched in 1964. The Beomaster 900 was a fully transistorized radio, equipped with FM stereo reception. Bang & Olufsen wanted to design a product that was so unique that it would open doors to distribution across Europe, just as the “Five Lamper” had done in Denmark 30 years earlier.
Beomaster 900M
This version of the Beomaster 900 was specially developed for users who were looking for a unit to use with external loudspeakers. Furthermore, the Beomaster 900M is identical to the Beomaster 900K. Dimensions: 146 mm high, 404 mm wide, 230 mm deep. Available in teakwood or Brazilian rosewood finishes.

The most striking aspect, however, was not in the technology, but in the design. Transistors are small compared with vacuum tubes and produce less heat. Because they require less space to vent that heat, they enable radically different housing designs. Architect and designer Henning Moldenhawer knew how to make the most of this. He designed the very first low, flat radio housing and thereby brought about a radical renewal. Virtually overnight, the familiar vacuum-tube radio became obsolete. From then on, devices were powered by transistors rather than tubes.

An elongated, low, fully transistor-based radio that was immediately ready to play — without the warm-up time required by vacuum tubes — in itself was a achievement. Moreover, the design concept challenged all conventional ideas about radio design. The new Beomaster 900 signified a revolution. Architect Henning Moldenhawer for the first time in the history of radio pulled the front panel through to the sides of the device. This broke with the traditional framing that had been used for radios, televisions, and loudspeakers up to that point.

The set was awarded the iF prize at the International Exhibition in Hanover. It is equipped with a specially designed, highly efficient two-channel audio amplifier for playing stereo records (delivers 2 x 5 watts of undistorted output power). A ‘Beo-Beacon’ indicator lamp lights up when the receiver is tuned to a transmitter broadcasting an FM stereo program, or when the unit is switched on to play stereo records or stereo tapes.
