- 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 This model reflected changing trends in sound reproduction, allowing audiophiles to upgrade outdated or broken components as needed.

Parking meters, introduced in Oklahoma City in 1935, proved to be the workable and enforceable solution. Carl Magee, inventor of the parking meter with help from local engineering professors and college students, named his company "Dual" -- supposedly because parking meters served the dual purpose of controlling parking and generating revenue.
