Since the beginning of 1957, the radiogamophon network tube lamp UP-2M was produced by the State Union Electrotechnical Plant Elfa and the Moscow Electric Machine Building Plant. The radiogramfon '' UP-2M '' is assembled on the basis of the previous model '' UP-2 '' and is not different from it in electrical circuit and design. The main difference of the model is the start of the electric motor with the help of tonearm and the presence of hitchhiking, after the end of the recording. The model uses a new tonearm, which was soon replaced by a more modern one. The network switch is combined with the volume control, and the motor switch is removed. The radiogram is also assembled with three radio tubes, two of which 6N9S and 6P6S operate in a low-frequency amplifier, and the third, 6C5S in a full-wave rectifier. The amplifier operates on a 1GD-5 loudspeaker, giving it an output power of up to 1 watt. The speaker system effectively reproduces the band of sound frequencies from 100 to 6000 Hz. The radiogramfoner loses ordinary and long-playing records, designed for a speed of 78 rpm, as well as long-playing records with compacted micro-recording and calculated for a speed of 33 rpm. Power consumption 60 watts. Dimensions of the device 160x350x260 mm. Weight 5 kg.
