- Dual Automatic Turntable, Model 1215S, 1970-1971 - This device is one part of a component stereo sound system. Component stereos were built up over time through the purchase of individual components that best suited the needs of a user: receiver-amplifiers, tape decks, speakers, turntables, and CD players. This model reflected changing trends in sound reproduction, allowing audiophiles to upgrade outdated or broken components as needed.
