Network tube radio receiver "Voronezh-58".
Tube radios.DomesticSince October 1957, the "Voronezh-58" network tube radio receiver has been producing the Voronezh Radio Plant. The Voronezh-58 radio receiver is a massive 4-tube superheterodyne of the fourth class. It is based on a 1954 Voronezh battery radio. The new receiver uses a case, chassis, KPE and IF circuit of the battery model. The Voronezh-58 radio is powered by an alternating current network of 127 or 220 volts. The receiver is designed to operate in the ranges of long (723 ... 2000 m) and medium (187.6 ... 577 m) waves. Sensitivity in both ranges is not worse than 400 μV / m. Selectivity in both ranges is not less than 16 dB with a detuning of ± 10 KHz. The converter uses a 6I1P radio tube, the same radio tube is used in the IF amplifier, it also works in the preliminary bass amplification stage, the final stage is made on the 6P14P radio tube. A germanium diode of the DGTs6 type operates as a detector. The rectifier uses a 6Ts4P kenotron lamp. A dynamic loudspeaker 1GD-9-140 is turned on at the output of the radio receiver. The nominal output power of the amplifier is 0.5 W. Power consumed from the network is not more than 30 W. The radio receiver case is made of plastic and has dimensions - 270x210x160 mm. The receiver weighs 4.2 kg without packaging. The price of the radio is 240 rubles before the 1961 reform. Together with the Voronezh receiver, since 1958, the plant has been producing the Strela radio receiver, similar in design, layout and design.
