Portable radio `` Sonata-201 ''.
Portable radio receivers and radios on p / p.DomesticSince 1972, the portable radio receiver "Sonata-201" has been produced by the Leningrad plant "Radiopribor". The 2nd class radio receiver `` Sonata-201 '' is designed to receive programs of radio broadcasting stations in the DV, SV and four HF sub-bands. It is developed on the basis of the Sonata receiver. Changes in the electrical circuit are aimed at increasing the output power up to 0.5 W and the convenience of tuning on the KB sub-bands. For this, the output triodes P41 were replaced with GT402A, and the wafer switch was replaced with a new push-button switch for six positions. This innovation made it possible to increase the number of KB sub-bands from two to four, and to make the 41, 31 and 25 meters stretched. In addition, the model uses an input circuit that is distinguished by noise immunity and high sensitivity. The external radio receiver has also changed, as well as the placement of its controls and scales. Power is supplied from 2 3336L batteries. The dimensions of the radio receiver are 198 x 270 x 78 mm. Weight 2 kg. The export version of the radio had HF sub-bands from 16 to 50 meters.
