Network tube radio receiver Belarus-53

Since 1953, the Minsk radio plant named after V.M. Molotov has been producing the network tube radio receiver "Belarus-53". The receiver is a 14-tube superheterodyne of the first class. The receiver has 6 ranges: DV, SV and 4 KV, of which 2 are semi-extended 30 ... 47 m and 48 ... 76 m and 2 are extended 25 and 31 m. In addition to smooth tuning, there is the possibility of fixed tuning to 6 radio stations: DV and 4 on NE. The transition from one radio station to another is carried out using a push-button switch. The receiver allows high-quality reception of local radio stations. To do this, he switches from a superheterodyne circuit to a direct amplification circuit. The receiver has a silent tuning unit. Tone control allows you to select the desired color of the sound. The receiver has two loudspeakers with a cone diameter of 220 mm, which, together with a large volume of the case, made it possible to obtain effective reproduction of low frequencies, starting from 50 Hz. Rated output power 4W. Sensitivity with smooth adjustment 50 µV, with a fixed 200 µV. Adjacent channel selectivity 46 dB. The power consumed from a network of 135 W. The receiver uses a drum-type switch. The receiver is built according to a block diagram, its chassis is a steel frame on which 6 blocks are installed: HF, blocks of IF, LF paths, power block, push-button settings, tone controls, volume and silent settings. The case is trimmed with walnut veneer and polished. A large horizontal scale and a massive handwheel on the axis of the tuning knob make it easy to operate. The weight of the receiver is 35 kg. The radio receiver was produced until 1962 in several design options for the case and the back wall.
