Sansui MD-5000
Little is documented about the Sansui MD-5000 apart from a burst of advertising that ran in the American hi-fi press in early 1968. Sansui's own ads, headlined "Suddenly it's 1969…", announced a solid-state stereo receiver whose IF section used four integrated-circuit components. That was a forward-looking feature at the time. The same advertising, carried in High Fidelity (April 1968, p.21) and Audio (April 1968, p.11), claimed flat frequency response from 15 to 40,000 Hz (one version of the ad cited 10 to 50,000 Hz). It also listed outputs for three separate sets of stereo speakers, and front-panel monitoring of two tape machines while recording through the receiver.
Beyond that short promotional run, the record is essentially empty. No independent test report, no service manual, and no confirmed production years or price have surfaced. The MD-5000 appears to have been advertised for a few months in 1968 and then dropped out of the record.
