The new model differs from the "Record-65" radio line in that the HF range is divided into two sub-ranges: KB1 76 ... 37.5 m (3.95 ... 8.0 MHz) and KB2 33.3 .. .24.8 m (9.0 ... 12.1 MHz). There is AGC, timbre tone control. The speaker system consists of two loudspeakers 1ГД-5 (1ГД-11). The following lamps were used in the radiometer: 6I1P, 6K4P, 6N2P and 6P14P. Sensitivity in the ranges of DV, CB - 200 µV, in the KB ranges - 300 µV. Selectivity at frequencies of 250 and 1000 KHz - 26 dB. When receiving, the AU reproduces the frequency band - 150..3500 Hz, when playing records 150..6000 Hz. Rated output power 0.5 watts. The power consumed from the network at reception 40, the operation of the EDA 55 watts. Dimensions of the model 620x255x295 mm. Its weight is 13 kg.
