Network tube radio receiver "Strela".
Tube radios.DomesticSince 1958, the network tube radio receiver "Strela" has been produced by the Voronezh Radio Plant. The radio receiver of the 4th class "Strela" is a three-tube superheterodyne designed for receiving radio programs in the long and medium wave ranges, as well as for listening to a recording with an external pickup. The sensitivity of the receiver, with an output power of 0.5 W and a sound pressure of 3.5 Bar, is not worse than 400 μV. Selectivity on the adjacent channel at a detuning of ± 10 kHz - 16 dB. IF = 465 kHz. The band of reproducible sound frequencies is 150 ... 5000 Hz with a nonlinear distortion factor of 5%. Powered by 127/220 VAC. Power consumption 40 watts. The receiver uses 6I1P (2), 6P14P (1) and 6Ts4P (1) radio tubes. The 6Ts4P lamp, used in the rectifier since 1960, was replaced by D7V diodes. The model uses an elliptical dynamic loudspeaker 1GD-9. The power supply is assembled according to a half-wave circuit, with a power transformer. The signal detector and the AGC system are made on the DG-Ts6 diode. 3-key switch turns the receiver on / off and switches the bands. Simultaneous pressing of the DV, SV keys turn on the adapter. This closes the input coils, eliminating interference with the reproduction of the recording if the receiver is tuned to a station. The dimensions of the receiver are 270x210x160 mm. Weight 4.2 kg. The ease of use of the receiver with good external design made it massive and cheap for its time. The price of the receiver is 281 rubles 50 kopecks.
