Marantz - SD-3000 Cassette recorder-player

I am selling a fantastic and rare Marantz SD-3000 stereo cassette deck, a true collector's item for vintage Hi-Fi enthusiasts. Produced between 1979 and 1981, this deck stands out for its robust construction and the brushed champagne-colored aluminum front panel.
