Stationary transistor radio `` Minsk ''.
Radiols and receivers p / p stationary.DomesticThe stationary transistor radio "Minsk" (a small series was called Minsk-T) has been producing the Minsk Radio Plant since the fall of 1959. The radio receiver `` Minsk '' was developed by engineers of the Minsk Radio Plant and employees of the A.S. Popov Leningrad Institute, abbreviated as IRPA. During development, it was planned to use two loudspeakers and a network power supply in the receiver, but in the process of release one loudspeaker was left, and the power supply from the network was sold separately. In 1962, the radio was modernized and received a power supply unit in the kit and a new name "Minsk-T". However, some batches of the "Minsk" receiver since 1960 already had a built-in power supply unit. Radio receiver "Minsk" dual-band DV 2000 ... 723 m and SV 577..187 m superheterodyne. Control is carried out by two knobs: Volume to the left of the scale and Setting, as well as a switch with three keys: off, DV and CB. Reception is made via an internal magnetic antenna or an external one. Loudspeaker used 0.5GD-11 (1GD-6, 1GD-9 in later editions). The circuit has seven transistors and a p / p diode. Powered by a 9 V battery, consisting of six Saturn cells, which are installed on the inside of the back wall of the case in two cassettes. The set is enough for about 100 hours of operation. The receiver can also be powered from the AC mains. When the network set-top box is turned on, the batteries are disconnected, and the power switch is switched to the mains winding circuit of the transformer. The receiver chassis consists of two blocks. The first contains a ferrite antenna, a push-button switch, a converter, a three-circuit IF filter and a KPE unit. Installation is carried out by conventional, surface-mounted installation. The second block is mounted by means of printed circuit wiring and contains the IF path and the LF amplifier. Receiver sensitivity in the LW range of 2.5 mV / m, SV range of 1.2 mV / m, with an external antenna of 150 μV. Selectivity 16 ... 20 dB. Operating frequency range 200 ... 3500 Hz. The maximum output power is 0.4 watts. Wooden case, polished. The dimensions of the receiver are 325x270x170 mm. Weight 4.5 kg. The price of a receiver without a power supply unit is 40 rubles 25 kopecks, with a power supply unit 47 rubles 15 kopecks from April 1961.
