Shure 3B Carbon Microphone (1930)


Shure 3B Carbon Microphone (1930)

THIS RADIO HAS BEEN SOLD!
Very nice and very old carbon mic, model 3B, serial #502; Shure 3B mics evoke the early days of radio broadcasts are highly coveted by radio mainly as collectibles/decorative items. It appears all original except for the cord. I don't have any way to test. Shure's foray into carbon microphones dates back to 1929, when Shure Brothers, then located at 335 West Madison Street in Chicago, began to transform itself from an AM radio kit parts company to the exclusive distributor for Ellis Electrical Laboratories. In 1932, the business relationship soured between Mr. Shure, then a young man, and Mr. Ellis, considerably older. Shure began manufacturing its own carbon microphones later that year. The primary applications for carbon mics were public address, broadcast, military operations, and telephony. The rugged mics offered a high output level and their simple construction made them relatively inexpensive to manufacture. They were widely used in World War II and in spite of technological advances, carbon microphones were used in telephones until the 1970s and 1980s.
