|Name:||Eimac (brand name) (USA )|
Eitel-McCullough, Inc.; various addresses: Brand: Eimac. Since 1958 the Eimac Division is headquartered in San Carlos, California.
The company's first products were transmitting vacuum tubes which operated at low voltages, a design feature driven by the needs of the Ham radio community.
Under the leadership of the founders, Bill Eitel and Jack McCullough, the company grew and expanded to meet the needs of the U.S. military, so that by 1945 it was shipping 3,500 tubes per day from two manufacturing plants. Following the end of the war, the company refocused on the commercial broadcast industry and developed new tubes for that application. Regarded as a technical innovator in the design of gridded power tubes, Eimac became the worldwide leader in the broadcast tube industry (Text published by CPI).
Officially one can read: "Since 1965 Eitel-McCullough (Eimac) has been merged with Varian Associates and became known as the Eimac Division." But the true story is that the much smaller Varian bought Eimac - but was wise enough to keep the name Eimac (info Mr. Ackeret).
In 1995, Leonard Green & Partners purchased the entire Electron Devices Business from Varian and formed Communications & Power Industries, Inc. This new company, with sales of $250 million, consists of the Beverly Microwave Division, Satcom Division, Microwave Power Products Division, Communications and Medical Products Division (located in Canada), and the Eimac Division.
