Description from the seller
Marantz ST500 vintage synthesizer AM/FM stereotuner in classic champagne gold finish, produced in the early 1980s (circa 1980–1982). Technically in 100% good working condition with fast, stable station locking and visually in neat vintage condition with light signs of use consistent with its age.
The tuner combines the classic Marantz aesthetics (beveled aluminum front in gold/champagne and solid knobs) with modern quartz-controlled digital tuning technology. The clear display shows the frequency digitally, complemented by a convenient multi-channel LED signal-strength meter and tuning indicator. Sonically, the ST500 delivers warm, spacious, and natural radio reception with a low noise floor and excellent stereo separation.
