A catalog of Technics auto-changer turntables from August 1977. Four direct-drive models: the SL-1650 at ¥59,800 and SL-1950 at ¥49,800 - both with automatic record stacking - alongside the SL-950 and SL-P50. The catalog’s central concept is “Sunday Morning Auto Changer”: load a stack of records and leave it running.
