Electric record players and electrophones on semiconductorsDomesticThe transistor network electrophone "Russia EF-327" has been produced by the Chelyabinsk PO Flight since 1987. Monophonic electrophone "Russia EF-327" provides reproduction of phonograms from mono and stereo phonograms in monophonic mode, as well as recording phonograms from phonograms to a tape recorder. The electrophone is distinguished by a newer element base, with the use of microcircuits in the ZCh amplifier, an electro-playing device of the 3-EPU-77SP type, with an automatic return of the pickup to its original position at the end of the treadmill of a gramophone record, by connecting headphones. The microphone uses a stereo phono head, which allows you to record from stereo records to a tape recorder. The disc rotation frequency is 33 and 45 rpm. The range of reproducible frequencies is 80 ... 12500 Hz. The detonation coefficient is not more than 0.25%. Background level minus 54 dB. Rated output power - 2x2 W, maximum 2x4.5 W. Speaker input impedance is 4 ohms. Supply voltage 220 V. Power consumption from the network 40 W. The dimensions of the microphone are 345x300x145 mm. Weight is about 5 kg.
