Overview
General Electric (GE) was one of the largest American manufacturers of vacuum tubes and electronic components during the 20th century. Through its Electronic Tube Department and related electronics divisions, GE produced receiving tubes, transmitting tubes, cathode-ray tubes, industrial tubes, and military electronic components for radios, televisions, communications systems, laboratory equipment, and industrial applications.
GE became a major force in vacuum tube manufacturing during the expansion of commercial radio broadcasting in the 1920s and remained one of the leading American tube producers throughout the vacuum tube era. The company manufactured a broad range of electronic tubes used in home entertainment equipment, military electronics, broadcast transmitters, scientific instruments, and early computers.
General Electric tubes were widely known for quality and reliability and were commonly used in OEM manufacturing as well as replacement service markets. GE also manufactured specialty industrial and transmitting tubes for commercial broadcasting, radar, aviation, and defense applications.
The company later expanded into semiconductors and solid-state electronics as vacuum tube demand declined during the 1960s and 1970s.
