*In consumer electronics, the word "set" -- e.g., "television set" -- indicates that all components required to make the device function (loudspeaker, power supply, transistors, vacuum tubes, etc.) are all installed at the factory. In the early and mid 1920s, all radios were sold "a la carte" -- i.e., the cabinet and chassis, speakers, tubes and power supply (usually a group of three or more wet cell storage batteries) were all purchased separately. With the introduction of alternating current power supplies in 1927, followed by the onset of the Great Depression, manufacturing radio sets rather than individual pieces improved safety and kept costs low.
