- Water Cooled Transmitting Tube, Used at W8XE Ford Motor Company Radio Station, 1925 - Vacuum tubes appear in older radios, televisions, amplifiers, computers, and other electronic devices. Their function: to amplify and strengthen weak electronic signals. Typical tubes are sealed glass bulbs evacuated of gas, allowing electron flow to be influenced by a cathode, plate and grid. This is a water-cooled version--a necessity to displace the intense heat generated by large, powerful tubes.
