Transistor network electrophone '' Nocturne-314-stereo ''.

Electric record players and electrophones on semiconductorsDomesticThe transistor network electrophone "Nocturne-314-stereo" has been produced by the Grozny Radio Engineering Plant since the 1st quarter of 1985. Electrophone is intended for reproduction of phonograms from mono and stereo phonograph records of any format. Electrophone amplifiers are assembled on transistors. It uses a two-speed electric player 2-EPU-62SP with a piezoceramic pickup head of the GZKU-631R type, a microlift and a hitchhiker when the needle enters the treadmill of the gramophone record. The electrophone has separate tone controls for HF and LF, a network LED indicator, electronic protection of the ULF against short-circuit in the load. The rated output power of the ULF is 2x3 W, the sound frequency range of the reproduced speakers is 60 ... 12500 Hz. The set includes two АС 6-АС-322. The dimensions of the microphone are 380x370x160 mm, the speaker is 360x250x205 mm. The mass of the microphone is 8.5 kg, the speaker is 3.5 kg. To increase the range of names of devices, the plant practically jointly from 1985 to the beginning of 1992 produced electrophones identical in design, electrical circuit and design, such as: "School-Stereo", "School EF-301S", "Sintar EF-302S" and " 302C-1 ".
