English: The radio engineering company in Přelouč was founded in 1921 by Ing. J. V. Myslík Hyršovský (Radiozávody Přelouč - J. V. Myslík-Hyršovský a spol.). In 1925 its name was extended to Radio Zenit Přelouč. In 1927 the plant was sold to the German concern Siemens-Halske and at the same time the Czech-German company Radiotechna systém Telefunken (abbreviated as Radiotechna Přelouč) was founded. In the 1930s, the factory was self-sufficient in the production of radiotechnical components for its own assembly of radio receivers of both medium and luxury class. During the Second World War, the Siemens concern focused on war production and the production of radio receivers was stopped in 1942. After the end of the Second World War in 1945, the business was transferred from its German owner (Siemens) to the victorious Soviet Union, which subsequently donated it to the restored Czechoslovak Republic. After the establishment (in 1946) of the national company TESLA, which united selected factories engaged in the production of low-current and radio technology in the territory of post-war Czechoslovakia, the company was renamed (around 1948) to Tesla Přelouč (an auxiliary plant of the branch company TESLA Hloubětín). The company was closed down in 1992.
