Experimental High Voltage Mercury Rectifier
- Annaka Wireless Works Electron Tube, 1916-1917 - Dr. Lee De Forest was an inventor, engineer, and the self-styled "Father of Radio." In 1906, De Forest invented the Audion tube, allowing the detection and amplification of weak radio signals. As the first triode vacuum tube, the Audion revolutionized radio broadcasting--and made it more practical. By the late 1920s, vacuum tube radios were the widespread in people's homes.

- Western Electric 100 Kilowatt Water-Cooled Triode, Type 298A, circa 1939 - 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.

- Amalgamated Wireless Electron Tube, 1920 - 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 an interior cathode, plate and grid. Perfected in 1906 by Lee De Forest, the vacuum tube was the genesis of a communications revolution.
