http://rf.kievrus.com/viewforum.php?f=601 Efim A. Levitin was born in Khislavichi of the Smolensk region in 1906. In school years he acquired knowledge of French, German and English. He got carried away by detector receivers. After graduation from school he worked as an installer of telegraph lines, then studied at the University of Smolensk.
In 1930, after graduation from the university, he worked at the Central Radio Laboratory in Leningrad (CRT), later transformed into the Institute of Broadcast Reception and Acoustics (IRPA), where he supervised a group that measured the characteristics of radio tubes, and by the second half of the 1930s E.A.Levitin was recognized as one of the main developers of radio receiving technology in the country. In 1936 and 1938 his first publications on electron radio tubes came out.
In 1937, when the USSR acquired the license from the American corporation RCA for the production of radio broadcasters and radio tubes in their country, Yefim Levitin was sent to the RCA Victor plant in Camden, New Jersey, USA, where he supervised the development of a 6-tube radio receiver 6H-1, 9-tube radio receiver 9H-4 and automobile radio in accordance with the technical specifications previously prepared by him. Yefim Levitin also supervised the purchase of American samples of items and materials for future manufacturing radio receivers by factories in his country. Reports on his business trips to the United States were published.
The purchase of the license and manufacturing radio receivers (the so-called "Russian Americans") in the USSR was extremely important for the radio industry of the country. First, the whole technological chain of assembly production immediately lined up with the world's most advanced cycle at that time. Secondly, the production of the newest radio tubes allowed the USSR to raise the existing backward technological production base to the modern level. Thirdly, even before the licensed radio tubes production line was constructed, some of the purchased radio tubes were immediately sent for development and production of professional and military equipment. And the newest samples of household radio devices after some modifications were used as professional devices. The colossal significance of the issue of licensed 6N-1 household receivers can be judged by the laconic phrase of the order of the USSR People's Commissar for Electrical Industry No. 348ss of December 15, 1941, paragraph 2a of which reads: "To organize the production of military radio stations according to the RB type from the details of the 6N-1 receiver ..
Upon his return to Leningrad, Yefim Levitin, under the auspices of IRPA, worked on the implementation of radio receivers of the 6N-1 on the basis of the American sample of the receiver into production at the Elektrosignal plant in the city of Voronezh.
At the beginning of the war in 1941, he was drafted into the military in the rank of Private, but at the moment of his registration at the military enlistment office of Leningrad, paramilitary messengers delivered the order of the People's Commissar of Defense to send him to the Voronezh plant, as a designer for the urgent shift to the production of radio equipment for the front.
In the fall of 1941, when the front line approached the city, he, together with the federal level leader Konstantin Nazarovich Meshcheryakov, organized the evacuation of the equipment and the employees of the Voronezh Electrosignal plant to Novosibirsk. Being the chief designer of the new Novosibirsk plant "Electrosignal", known in those years as Plant # 590, A. Levitin contributed to the development and production of radio stations for tanks, airplanes and infantry, and to the fast setting the enterprise in motion. In 1942, the plant was mentioned as the only plant in the NCEP system, which was able to begin production of military equipment very fast, thanks to the fact that they had evacuated both all equipment and all necessary available materials. The imported licensed receivers and radio tubes played a significant role in those achievements.
In 1944, the plant and its director K.N Meshcheryakov were awarded with the Order of Lenin, and one of the four main specialists, who made special contributions and were awarded with the Order of"Red Star, was Yefim Alekseyevich Levitin.
In 1946 E.A. Levitin was sent to Moscow to the Ministry of Electrical Industry of the USSR. Then, in 1947 he had a difficult time as his only source of income was limited to publication of directories on radios, but that made him very popular among radio amateurs. Some of those directories are still popular.
Later, Yefim Alekseevich Levitin, a born teacher and organizer, taught radio engineering at the Moscow Electromechanical Technical School and at the Moscow Radio Instrument-Making College.
Was married. Sons - Leonid and Alexander. Efim .A. Levitin wrote several books in co-authorship with Leonid.
On the website of the russian Radio Front there is a separate forum called "Yefim Alekseevich Levitin", where EA. Levitin is called the father of "Russian Americans", referring to his services in the development and mass production of 6H-1 and 9H-4 receivers, under the RCA license, in the USSR.
