Transistor network electrophone '' Electronics EF-017-stereo ''.
Electric record players and electrophones on semiconductorsDomesticTransistor network electrophone "Electronics EF-017-stereo" since 1985 has been produced by the Kazan Scientific and Production Association "Elecon". Electrophone is designed for high-quality reproduction of recordings from mono and stereo phonograph records. The electrophone consists of an "Electronica EP-017S" electric player, a full audio frequency amplifier "Elektronika 50U-017S" and two acoustic systems of the 35AS-215 type. The lightweight tonearm of the turntable and the magnetic head ГЗМ-043 with the increased flexibility of the moving system reduce the wear of the plates. Dynamic damping of the main resonance of the tonearm allows even warped records to be played without noticeable degradation. The player is equipped with a quartz stabilization of the rotational speed of the disc, regulators of the clamping and anti-skating forces. The AF amplifier is equipped with a relay protection system against overload and short circuit in the load. The microphone allows two pairs of speakers to work at once, either of which can be turned off. EP characteristics: The range of reproducible frequencies is 20 ... 20000 Hz. Knock coefficient - 0.1%.
