Tube radios.DomesticSince 1956, the network tube radio receiver "Sadko" has been produced by the Moscow Radio Plant "Krasny Oktyabr". The network tube receiver `` Sadko '' was developed as promising for mass production. The receiver was among the first models to use finger-type radio tubes. The radio receiver is a seven-lamp superheterodyne of the second class, operating in the ranges: DV - 2000 ... 723 m, SV - 577 ... 187 m, HF, two sub-bands 76 ... 39 m and 39 ... 24.8 m and VHF-FM in the range of 4.66 ... 4.11 m. The radio receiver has a separate tone control for LF and HF, an AGC system. VHF-FM radio stations are received on an internal dipole antenna. The speaker has four loudspeakers; two broadband and two high-frequency. The rated output power of the LF amplifier is 2 W. The range of reproducible sound frequencies with radio reception of AM radio stations and the pressed key `` MP '' is 80 ... 8000 Hz, with radio reception in the VHF-FM range, the audio frequency band is 80 ... 12000 Hz. The receiver is powered by the electrical network. Power consumption approx. 60 W. Receiver dimensions 615х340х290 mm, weight 18 kg. For unknown reasons, only about one thousand receivers were produced.
