Network tube radio receiver `` Neva-51 ''.
Tube radios.DomesticSince 1951, the radio receiver "Neva-51" has been produced by the Leningrad plant named after Kozitsky, the Leningrad metalware plant and the Leningrad mechanical plant "Leninets". The radio receiver `` Neva '' from 1948 produced by several factories in 1949 was transferred to the metalware plant to increase production. The plant began modernizing the radio and from the beginning of 1951 produced it as a new model. Since spring, the modernized receiver has been produced by two more Leningrad plants. In comparison with the previous receiver, the stability of the local oscillator frequency has been increased; the mirror signal is weakened and the tendency to excitement at frequencies close to it is eliminated; improved selectivity; lightened lamp operating modes; improved frequency response of the entire path; the mounting of the receiver was slightly changed, a number of other minor improvements in the circuit were made. The design and layout of the main nodes remained the same. Ranges: DV - 150 ... 420 kHz, SV - 520 ... 1500 kHz, KV3 - 4.2 ... 8 MHz. KV - 2 9 ... 13 MHz. KV-1 - 14.9 ... 15.6 MHz. IF 465 kHz. Output power 4 watts. Power consumption 100 watts. Dimensions of the model are 580x372x280 mm. Weight 20 kg.
