Transistor network electrophones '' Russia-321-stereo '' and '' Russia-321-1-stereo ''.
Electric record players and electrophones on semiconductorsDomesticTransistor network electrophones "Russia-321-stereo" and "Russia-321-1-stereo" since 1983 and 1985 have been produced by the Chelyabinsk PO "Flight". Both models of electrophones practically do not differ in design, there are minor differences in the electrical circuit, but for the second model the price has been reduced from 109 to 80 rubles. Stereophonic electrophone "Russia-321-stereo" provides reproduction of sound recordings from stereo and monophonic gramophone records. It consists of the III-EPU-74SP electro-playing device and a two-channel amplifier, combined in one housing, and external acoustic systems. The desired sound tone is set using separate tone controls for high and low frequencies. It is possible to connect a tape recorder and a radio broadcasting network to the amplifier. The bodies of the blocks are lined with fine wood veneer. The main technical characteristics of the models: Rotational speed of the disk - 33, 45 and 78 rpm. The range of reproducible frequencies is 80 ... 12500 Hz. The nonlinear distortion factor of the amplifier is not more than 2.5%. Rated output power 2x2 W, maximum 2x5 W. The input impedance of the speaker is 4 ohms. Power supply from 220 V. Power consumption - 40 W. Dimensions of the microphone 395x325x165 mm, one speaker 363x270x140 mm. The mass of the set is 15.5 kg. The models are based on the Accord-201-stereo electrophone. Since 1985, the electrophone "Russia-321-stereo" has also been produced by the Makhachkala Radio Goods Plant.
