The SD-7000 was Sansui's flagship effort in the tape deck market. It was heavily built, boasting solenoid/relay-operated transport controls that make it incredibly quiet and accurate. Because it contains a dedicated playback head for both the forward and reverse directions, it supports true auto-reverse, as well as repeat, rewind, and automatic shut-off functions

The Sansui SD-7000 is a premium, 4-track, 2-channel stereo reel-to-reel tape deck released in the early 1970s.Known for its robust build, it features 3 motors, 4 heads (including auto-reverse playback), and handles 7-inch reels beautifully. It requires an external amplifier or receiver to play. [1, 2, 3, 4]
