Radio Baku network lamp "Baku-58" and "Baku-58M" from 1958 and 1961 was produced at the Baku Radio Plant. Radiol "Baku-58" is a 7-tube AM-FM combined superheterodyne with a universal EPU. It is designed to receive radio stations and play records. The model has a VHF dipole, a key type switch, an optical adjustment indicator, automatic gain control, separate tone control for bass and treble, IF bandwidth adjustment and wideband speakers. When you receive a FM radio, you can get a high quality sound. The speaker consists of four loudspeakers: two wideband 2GDZ and two high frequency 1GD9 located on the side walls of the case. The EPU-1P type EPU has an asynchronous type motor with a two-speed drive, with semi-automatic switching on and automatic switching off, a piezoelectric pickup. Radiol is powered from an AC network with a voltage of 110, 127 or 220 V. Radiola is framed in a case trimmed with fine wood. The scale has a graduation in meters. The names of cities with powerful stations are plotted on the Far East, North-West bands on the scale. The following lamps are used: 6NZP UHF, VHF UHF converter and local oscillator, 6I1P UPCH UHF UHF range, local oscillator and AM converter. 6K4P UPCH AM signals. 6H2P detector AM, FM signals. 6H2H "‹"‹preamplifier bass. 6P14P terminal ULF. 6E5C indicator settings. There are external antenna and grounding sockets, external (or internal) VHF antenna, external loudspeaker and pickup. Ranges: LW, MW, KB-2 - 3.9 ... 7.6 MHz. HF-1 - 8.2 ... 12.4 MHz. VHF - 64 ... 73 MHz. IF: on the 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 watts. When receiving a frequency band: in AM 100 ... 4000 Hz, FM 100 ... 7000 Hz, with an EPU 100 ... 5000 Hz. The power consumption at the reception of 60 W, when the EPU is 75 W. Dimensions radiograles 570x370x370 mm. Weight 22 kg.In 1961, the Baku-58 radio is upgraded to Baku-58M. In addition to changes in some of the values "‹"‹in the scheme and appearance, there are no other changes.
