label: Description (Brief)
content: In 1947 researchers at Bell Labs invented the transistor, a solid state alternative to vacuum tubes. Those new transistors needed to interface with existing equipment designed with tube sockets. This Fetron unit was specifically designed to replace a vacuum tube in a common tube socket, and shows an important aspect of new technologies—the need to be backwards compatible with existing devices.
