Radiola "Volga" since 1957 was produced by the Rybinsk Instrument Making Plant. The radiola is built on a unified chassis of the 1st class radio. In terms of design and circuitry, it is similar to the Comet, Zhiguli, and Octave radios, although the latter has a slightly different design of the case. All models are designed to receive broadcasting stations operating in the DV, CB, HF and VHF bands. The HF range is divided into two subbands. An internal rotary magnetic antenna is used for reception in the LW and CB ranges, and an internal dipole in the VHF range. There is a tone control for bass and treble, loudness with loudness, smooth bandwidth control for the IF AM path, AGC. Two front speakers 2GD-3 and two side speakers 1GD-9 are installed in the speakers. When receiving on VHF and playing phonograph records, AC radio sets provides a frequency band of 50 ... 10000 Hz. The sensitivity of the receiver when working with an external antenna in the range of LW, MW and HF is about 100 μV, in the VHF range of 20 μV, when working with a magnetic antenna in the ranges of MW, LW no worse than 10 mV / m. IF tract AM 465 kHz, FM path 8.4 MHz. The bandwidth on the IF AM path is continuously adjustable from 3.5 to 8 kHz. The FM bandwidth is 160 kHz wide. Adjacent channel selectivity in the AM path is from 30 to 70 dB, depending on the IF bandwidth, in the FM path 26 dB. The rated output power of the amplifier is 2 watts, maximum 4 watts. Pickup sensitivity 250 mV. In 1961, the radiola was modernized, a new case with straightened corners was developed. However, there were few such Volga radiol and in the beginning of 1963 it was discontinued. When developing the Volga radio, back in 1956, it was supposed to be released in 2 design options, one as in the above photos and the second in Art Nouveau style with tweeters placed at the corners of the front pillars of the case. In this case, the first option was planned to replace the second option from the second quarter of 1958. But probably not fate, there was no second radio option.To increase the range of products and names, the plant together with the Ordzhonikidze Sarapul Plant used the common radio model and the common backlogs of both plants to produce the Comet model, so on some copies of the Volga radio you can find a scale and a back cover called Comet or the Volga radio scale, and the Comet sticker on the back.
