Eimac
From Wikipedia, the free encyclopedia
Eimac is a registered trademark used by the Microwave Power Products Eimac operation of CPI Communications & Power Industries. Eimac makes vacuum tubes for radio frequency applications such as broadcast and radar transmitters. Eimac was a trademark of the Eitel McCullough Corp., founded by Bill Eitel and Jack McCullough in 1934 and later merged with Varian Associates in 1965, although it continues to operate as a separate business unit, and remained so when Varian's entire electron device business was spun off as CPI in 1995.
Eimac had a plant in San Bruno, California and, for a number of years, operated an FM radio station, KSBR, which was one of only two FM stations in the United States to test the new Rangertone tape recorders (adapted from the German Magnetophon recorders),[1] beginning in 1947. When the company outgrew its San Bruno facility, and was unable to expand there, it moved to San Carlos, California on April 16, 1959.[2]
