The Stereomaster was the precursor to the magnificent Beocord 2000.
It was a fully solid-state machine with three heads and an 8-watt per channel amplifier which could be used as a stereo system. To that end, provision was made for two sets of speakers, and a comprehensive array of stereo (mixable) inputs.
The first model available was the white version from 1963, available as a two or four track .
