Network tube radio receiver "Daugava".

Tube radios.DomesticSince 1954, the Daugava network tube radio has been produced by the Riga Popov Plant. The first releases of the receiver were called "Santa". Until 1956, the design of the radio was similar to the Daugava radio, with an opening scale (main and 4th photo). It was possible to supplement the receiver with the corresponding EPU and a radio tape was obtained. At the end of 1955, a custom design for the radio was developed. "Daugava" is a 6-tube superheterodyne receiver of the second class, designed to receive radio stations in the DV, SV and two HF sub-bands: 23.95 ... 7.4 MHz and 9.4 ... 12.1 MHz. Adjacent channel selectivity 34 dB. Sensitivity 50 μV on all ranges. Rated output power 2 W. The control knobs are located in the niches on the side walls. The scale is horizontal with a slope, where, in addition to the divisions indicating the frequency, the names of the DV and SV radio stations are marked.
