The radio gramophone `` UP-2 '' is assembled on 3 radio tubes, two of which, 6N9S and 6P6S, operate in a low frequency amplifier, and the third, 6Ts5S, in a full-wave rectifier. The LF amplifier is loaded onto the 1GD-1 loudspeaker, giving it a nominal output power of 0.5 W. The speaker reproduces the frequency range from 150 to 6000 Hz. The radio gramophone plays ordinary records at a speed of 78 rpm and long-playing at the same speed, but with a compressed microrecord, or long-playing records, designed for a speed of 33 rpm. The radio gramophone consumes 50 watts from the mains. Dimensions of the radio gramophone 398x294x168 mm. Weight 10 kg.
