Radiola network lamp `` Volga ''.

Network tube radiosDomesticRadiola "Volga" since 1957 was produced by the Rybinsk Instrument-Making Plant. Radiola is built on a unified 1st class radio receiver chassis. In design and electrical circuit, it is similar to the Kometa, Zhiguli and Octava radios, although the latter has a slightly different case design. All models are designed to receive broadcasting stations operating in the DV, MW, HF and VHF bands. The HF band is split into two sub-bands. For reception in the LW and MW ranges, an internal rotary magnetic antenna is used, and in the VHF range, an internal dipole. There is a tone control for bass and treble, loudness with loudness, smooth band adjustment for the IF of the AM path, AGC. The speakers are equipped with two front loudspeakers 2GD-3 and two side loudspeakers 1GD-9. When receiving on VHF and playing gramophone records, the AC radio provides a frequency band of 50 ... 10000 Hz. The sensitivity of the receiver when working with an external antenna in the LW, MW and HF ranges is about 100 µV, in the VHF range of 20 µV, when working with a magnetic antenna in the MW, LW ranges, no worse than 10 mV / m. IF path AM 465 kHz, path FM 8.4 MHz. The bandwidth for the IF of the AM path is infinitely adjustable within the range from 3.5 to 8 kHz. The FM bandwidth is 160 kHz. Selectivity on the adjacent channel in the AM path is from 30 to 70 dB, depending on the IF bandwidth, in the FM path is 26 dB. The nominal output power of the amplifier is 2 W, the maximum is 4 W. Pickup sensitivity 250 mV. In 1961, the radio was modernized, and a new case with straightened corners was developed. However, few of these "Volga" radios were produced and at the beginning of 1963 it was discontinued. When developing the Volga radio, back in 1956, it was supposed to release it in 2 design options, one as in the above photos and the second, in the Art Nouveau style with HF loudspeakers placed at the corners of the front pillars of the case. At the same time, it was planned to replace the first option with the second option from the second quarter of 1958. But probably not destiny, there was no second version of the radio. To increase the range of products and names, the plant, together with the Ordzhonikidze Sarapul Plant, used a common radio model and the common groundwork of both plants for the production of the "Comet" model, therefore, on some copies of the "Volga" radio, you can find a scale and a back cover with the name "Comet" or a scale from the "Volga" radio, and on the back cover there is a sticker "Comet".
