Since the fall of 1936, the lantern grid SVD-1 radio receiver produced Aleksandrovsky Plant No. 3 NKS. Radio "SVD-1" (Network, All-Wave, with Speaker, 1st serial model) was developed by experts of the American company RCA in the summer of 1936, based on the receiver "RCA-140". To monitor the development and procurement of components in the United States, a delegation of Soviet specialists was present for six months. As a result, by the autumn of 1936, the main components were purchased to start the serial production of the SVD-1 receivers in the USSR. Purchased components were enough to release five thousand radios. For the release of more radios, the missing components were planned to be made independently. The release was designed for 20 thousand radio receivers '' SVD-1 '', but it was released about 10 thousand plus about 5 thousand as military communication and broadcasting receivers. The upgraded case for the receiver "SVD-1", as well as for the "SVD", was used from a more modern receiver, "RCA T-10-1", produced in 1935 and manufactured in the USSR. The chassis was also manufactured in the USSR. Even during the development, our specialists immediately began to correct the documentation. The receiver was designed as a 9-tube, with a setting indicator and some other service amenities, the presence of which our experts found unnecessary and removed them. So the back cover of the device was removed, and the case is simplified. The situation was saved by a large reserve of cases for receivers '' SVD '', which was used also for the release of receivers '' SVD-1 '', therefore, a receiver is a rarity in a simple design. Unlike the "SVD" radio receiver, the "SVD-1" receiver was developed on radio tubes mainly of 6-volt series and according to the scheme was very different from its predecessor. It should be added that the abbreviation '' SVD '' originally gave a different meaning, it is the Soviet, All-Wave, Long Range. The network all-wave radio receiver of the first class '' SVD-1 '' was completed with American radio tubes.Attempts to replace the lamps with domestic ones did not have much success, such cases were quite rare and were advisory in the repair of the receiver. The radio receiver has 4 wave bands: "A" - long waves 150 ... 400 kHz, "B" - medium waves 540 ... 1500 kHz, "G" - short waves 1: 3.3 ..9 MHz, "D "- short waves 2: 8.5 ... 18 MHz. The intermediate range 77 ... 200 meters in this model was absent. The overlap on the edges of the ranges is 10% of the frequency. Rated output power 2.5 watts, maximum 7 watts. The frequency range on the loudspeaker factory development 80 ... 5000 Hz. The dimensions of the receiver are 560x360x290 mm. Power transformer from the network 110, 127, 220 V. Power consumption 80 watts. The receiver is assembled in a lacquered wooden case. Control knobs 4. The first one is the A-BD-D range switch, then the tuning and volume. Bottom knob - treble combined with a network switch. Radio "SVD-1" was produced until the autumn of 1937, after which the plant began production of a modernized radio receiver completely domestic development with the name "SVD-M".
