Transistor network electrophone "Sputnik-304".

Electric record players and electrophones on semiconductorsDomesticSince the beginning of 1987, the Sputnik-304 transistor network electrophone has been produced by the Leningrad Electromechanical Plant Sputnik. The network transistor microphone "Sputnik-304" is designed to reproduce sound recordings from gramophone records of all formats. The model consists of a case, an electro-playing device of the 3-EPU-38MP type, a low-frequency transistor amplifier and a built-in speaker system with a 3GDSH-2-8-100 loudspeaker. Rated output power 1.5 W, maximum 3 W. The range of reproducible sound frequencies by sound pressure is 125 ... 7100 Hz. Power consumption from the network is 25 watts. The frequency of rotation of the EPU disk is 33 rpm. The mass of the microphone is 7 kg.
