Network tube radio receiver '' SVD-1 ''.
Tube radios.DomesticSince the autumn of 1936, the network lamp radio receiver "SVD-1" has been produced by the Aleksandrovsky plant No. 3 NKS. The radio receiver "SVD-1" (Network, All-wave, with a speaker, 1st serial model) was developed by the specialists of the American firm RCA in the summer of 1936, based on the receiver "RCA-140". A delegation of Soviet specialists was present for six months to monitor the development and purchase of components in the United States. As a result, by the fall of 1936, the main components were purchased for the start of serial production of the SVD-1 receivers in the USSR. The purchased components were enough for the production of five thousand radio receivers. For the release of more radios, the missing components were planned to be made independently. The release was designed for 20 thousand SVD-1 radio receivers, but about 10 thousand plus about 5 thousand were produced as military communications and radio broadcasting receivers. The modernized case for the SVD-1 receiver, as well as for the SVD, was used from the more modern RCA T-10-1 receiver - produced in 1935 and manufactured in the USSR. The chassis was also manufactured in the USSR. Even in the course of development, our specialists immediately began to correct the documentation. The receiver was designed as a 9-tube receiver, with a tuning indicator and some other service amenities, the presence of which our specialists considered unnecessary and removed them. So the back cover of the device was removed, and the case was simplified. The situation was saved by a large backlog of cases for SVD receivers, which was also used for the production of SVD-1 receivers, so a receiver in a simple design is a rarity. Unlike the SVD radio receiver, the SVD-1 receiver was developed on radio tubes mainly of the 6-volt series and differed in many ways from its predecessor in terms of the scheme. It should be added that the abbreviation `` SVD '' was originally given a different meaning, this is Soviet, Vsevolnovy, Long-range reception.
