"Eimac" tubes ; vacuum tubes ; transmitting tubes ; Klystrons ; industrial magnetrons ; tetrodes-pentodes ; triodes ; diodes-rectifiers-pulse modulators ; founded in 1934 as Eitel-McCullough, Inc. 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 in World War II, 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. http://www.scripophily.net/eimcincca19.html ; During World War II, Eimac and other local tube corporations supplied these tubes in mass quantities to the US military where they powered high frequency radar sets and radio communication transmitters. http://nobelprize.org/physics/articles/lecuyer/
