Since 1951, the Neva-51 radio receiver has produced the Kozitsky Leningrad Plant, the Leningrad Metal Product Plant, and the Leninets Leningrad Mechanical Plant.
Since 1948, the Neva radio receiver, produced by several factories, was also transferred to the metalware plant to increase output.
The plant began the modernization of the radio and from the beginning of 1951 it was released as a new model.
In the spring, two more Leningrad plants produced the upgraded receiver.
Compared with the previous receiver, the stability of the local oscillator frequency was increased;
the mirror signal is weakened and the tendency to excitation at frequencies close to it is eliminated;
improved selectivity;
light modes of lamps are facilitated;
improved frequency response of the entire path;
The installation of the receiver has been slightly changed, a number of other minor improvements in the circuit have been made.
The design and layout of the main nodes remained the same.
Ranges: LW - 150 ... 420 kHz, CB - 520 ... 1500 kHz, KB3 - 4.2 ... 8 MHz.
HF - 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.
