(1968-1972) FM stereo tuner
Type numbers: 2005, 2013
The tuner part of the Beolab system, and the first “serious” Hi-Fi radio to be produced by B&O. The quality of construction of this model went even beyond B&O’s normal high standard, in particular the casework was manufactured to professional standards, as the Beomaster 5000 was intended for broadcast as well as domestic applications.

Electronically, nothing was spared to make the performance as good as possible, and each set was tested to ensure that it complied with the published specifications, the test report being included with the documentation for the user’s records. Many advanced features could be found in the circuitry, including ceramic IF filters, an FET front end with separate oscillator, a limiter stage preceding the discriminator stage, a stabilised power supply with two voltage rails and a pair of 19/38kHz tuned filters in the final audio stage.

The clean, pure styling hid the complexity of what was inside well, though there were more controls on the back, allowing the user to set the muting level, the level at which the stereo decoder switched in and the strength of the output to the amplifier. Both DIN and RCA type connectors were provided for amplifier connection, and a second DIN socket enabled a tape recorder to be independently connected. In the context of the full Beolab system this made it possible to record a radio program whilst listening to the record player. An interesting feature was the “monitor” aerial socket, heavily attenuated and intended for monitoring the output of a transmitting station. Just like the Beovision 3000, Beomaster 5000s found use to ensure that the broadcast signals were of an appropriate quality. Text copyright © Beocentral. Unauthorised reproduction prohibited.
Of course the main partner for Beomaster 5000 would have been the Beolab 5000 amplifier, but B&O suggested other systems too. Strangest of these was using Beogram 1500 as the amplifier, as this was fitted with a socket for a stereo tuner. Beovox loudspeakers such as the 600 or 1000 models would have completed this system, which would have left the tuner as by far the most expensive part! A more sensible alternative would have been Beomaster 5000 and Beocord 2400. This would have formed a compact system that could make excellent recordings of radio programmes, though the power output would have still only been 2x10W. Text copyright © Beocentral.

The high quality and great popularity of Beomaster 3000 saw the Beolab system disappear from the range, and for a while no separate tuner was offered. After a few years the Beomaster 1700 appeared, and even though the styling was very similar, the die cast chassis and test report had gone, re-organisation of the range and advances in production technique meant that it was a far simpler machine, and was never intended to adopt the “top of the range” position that Beomaster 5000 had occupied.
