Radiola network lamp `` Neva ''.

Network tube radiosDomesticThe network tube radio "Neva" in 1957 was prepared for production at the Leningrad plant "Radist". The network radio "Neva" is designed to receive broadcasts from radio stations operating in the DV and SV bands, as well as to play regular and LP records. The following lamps are used in the radio: 6A7 in the frequency converter; 6K3 in the IF amplifier; 6Н9С in the detector and LF preamplifier for reception and a two-stage amplifier for playing phonograph records; 6P6S in the final bass amplifier; 6TS5S in the rectifier. At the output of the final stage of bass amplification, two loudspeakers 1GD-5 are switched on. The adjustment knob is located on the right side of the case. Sensitivity 200 μV / m. Rated output power 1 W. The frequency response of the entire path in terms of sound pressure with an evenness of 14 dB at frequencies above 250 kHz and 18 dB at frequencies below 250 kHz, not more than 150 ... 3500 Hz. The dimensions of the radio are 415x325x315 mm. Weight without packaging 13 kg. The power consumed from the network when receiving 50 W, when the EPU is working 55 W. In terms of its parameters, the radio receiver meets the requirements of GOST 5651-51 for class 3 receivers. The radio is equipped with a small-sized electric player EMU-56 `` Swallow '', equipped with a hitchhiker. The same was installed in the serial Lastochka electric player. Radiola `` Neva '' cannot be considered modern for 1957, since it uses outdated lamps and nodes with large dimensions. But taking into account the increased demand of the population for simplified radios and the absence of such radios in production, the temporary release of the Neva radio is allowed by the MMP, until the organization of the release of more advanced radiols. Whether the radio was released or not is not established.
