Hytron Radio & Electronics Corporation

Overview

Hytron Radio & Electronics Corporation was an American manufacturer of vacuum tubes and electronic components active during the early and mid-20th century. The company became widely known for producing receiving tubes used in radios, televisions, military electronics, communications systems, and industrial equipment.

Founded during the early years of commercial radio, Hytron developed a strong presence in the replacement vacuum tube market as well as OEM manufacturing. The company produced receiving tubes, transmitting tubes, rectifiers, and specialty electronic components used in consumer and professional electronics equipment.

During World War II, Hytron expanded production to support military electronics manufacturing, supplying vacuum tubes for communications and radar systems. Following the war, the company continued growing as television ownership expanded across the United States.

In 1951, Columbia Broadcasting System (CBS) acquired Hytron Radio & Electronics Corporation. After the acquisition, products were commonly marketed under the CBS-Hytron brand name. CBS continued manufacturing vacuum tubes for television, radio, and industrial markets through the 1950s and 1960s.

CBS-Hytron tubes became common replacement parts sold through electronics distributors, repair shops, and parts stores throughout North America.
