Network tube radios '' Baku-58 '' and '' Baku-58M ''.

Network tube radiosDomesticNetwork tube radios "Baku-58" and "Baku-58M" have been produced since 1958 and 1961 at the Baku Radio Plant. Radiola "Baku-58" is a 7-tube combined AM-CHM superheterodyne with a universal EPU. It is designed to receive radio stations and play records. The model has a VHF dipole, a key-type range switch, an optical tuning indicator, automatic gain control, separate tone control for bass and treble, IF bandwidth control and a broadband speaker. When receiving an FM radio, it allows you to get high sound quality. The speaker system consists of four loudspeakers: two broadband 2GDZ and two high-frequency 1GD9 located on the side walls of the case. EPU type EPU-1P has an asynchronous type electric motor with a two-speed drive, with semi-automatic switching on and off, piezoelectric pickup. The radio is powered from an alternating current network with a voltage of 110, 127 or 220 V. Radiola is decorated in a case trimmed with valuable species of wood. The scale is graduated in meters. On the DV, SV bands, the names of cities with powerful stations are marked on the scale. Applied lamps: 6NZP UHF, converter and local oscillator of VHF range, 6I1P UPCH of VHF range, local oscillator and converter on AM bands. 6K4P UPCH AM signals. 6Х2П detector of AM, FM signals. 6H2H ​​LF preamplifier. 6P14P terminal ULF. 6E5C tuning indicator. The radio has sockets for an external antenna and grounding, an external (or internal) VHF antenna, an external loudspeaker and a pickup. Ranges: DV, SV, KB-2 - 3.9 ... 7.6 MHz. KV-1 - 8.2 ... 12.4 MHz. VHF - 64 ... 73 MHz. IF: AM path 465 kHz, FM 8.4 MHz. Sensitivity in: AM 200 μV, FM 20 μV. Selectivity in AM 30 dB, FM 26 dB. Rated output power 2 W. When receiving, the frequency band: in AM 100 ... 4000 Hz, FM 100 ... 7000 Hz, during operation of the EPU 100 ... 5000 Hz. Power consumption when receiving 60 W, when operating the EPU 75 W. The dimensions of the radio are 570x370x370 mm. Weight 22 kg. In 1961, the Baku-58 radio was modernized into the Baku-58M. Apart from changes in some denominations in the scheme and appearance, there are no other changes.
