Transistor network electrophone '' Nocturne-201 ''.
Electric record players and electrophones on semiconductorsDomesticSince 1973, the transistor network electrophone "Nocturne-201" has been produced by the Grozny Radio Engineering Plant. '' Nocturne-201 '' is a desktop version of the 2nd class electrophone, powered from an alternating current network. It is intended for listening to long-playing or ordinary gramophone records on the built-in 2GD-22 loudspeaker. The circuit of the electrophone is similar to that of the Accord-201 electrophone, differing in the use of a transformer to match the ULF with a loudspeaker. Basic technical data: The rotational speed of the turntable disk is 33, 45 and 78 rpm. The sensitivity of the amplifier from the input of the pickup / line is 150 mV / 15 V. The band of reproduced sound frequencies by sound pressure is 100 .... 10000 Hz. The relative noise level is -40 dB. Output power: nominal - 1.5 W, maximum 2 W. Adjusting the tone of sound frequencies: low 16 dB, high 14 dB. The range of manual volume control is not less than 40 dB. Power supply - alternating current network with voltage of 127 or 220 V and frequency of 50 Hz. Power consumption 20 W. Electrophone dimensions 420х310х190 mm. Weight 8.5 kg.
