- Western Electric Transmitting Tube, Type 270-A, Used at Radio Station WWJ, Detroit, Michigan, circa 1935 - Vacuum tubes appear in older radios, televisions, amplifiers, computers, and other electronic devices. Their function: to amplify or transmit electronic signals. Typical tubes are sealed glass bulbs evacuated of gas, allowing electron flow to be influenced by an interior cathode, plate and grid. Perfected in 1906, the vacuum tube was the genesis of a communications revolution.
