BeoMaster 5000 (1967)

BeoMaster Tuner/Amplifier

Production: 1967 - 1972

Designer: Jacob Jensen

Documents: Brochure, Service Manual

Beomaster 5000 was one of the components of the first ‘true’ Hi-fidelity units that Bang & Olufsen ever created. Designed by the pen of Jacob Jensen, the Beolab 5000 System - made up of two main components: the Beolab 5000 amplifier and the Beomaster 5000 tuner - was, from the outset, an object for pure audiophiles and broadcasters alike.

With the emphasis on quality, each Beomaster 5000, before it was shipped from the factory in Struer, was rigorously checked to ensure that it matched the exacting specifications that had been designed for it. A test report was provided for the prospective purchaser as proof.
