Since 1953 and 1956, the radio channel network lamp "Araz" and "Araz-M" produced the Baku Radio Plant. "Araz" in translation from Azerbaijani into Russian is the Araks River. Radiol consists of 6 tube; 6Ð7, 6Б8С, 6Ð9С, 6П6С, 6Е5С and 6Ц5С of a radio receiver and two-speed EPU, with an asynchronous motor and piezoelectric pickup with corundum needles. Ranges: DV and SV standard, KV1 3.95 ... 8.15 MHz and KV2 9.99 ... 12.2 MHz. Sensitivity to LW, MW 200, HF 300 µV. 26 dB selectivity. IF 465 kHz. The range of sound frequencies when playing records 200 ... 7000 Hz, while receiving radio stations 200 ... 3500 Hz. Rated output power on loudspeakers 1GD-6 1.5W. Power consumption is 50 W when the EPU is working and 35 W during radio reception. At the left, on the side of the case, there are tone and volume controls, on the right, the settings, the switch of ranges and the mode of playing records. In 1956, the model was upgraded to the "Araz-M" radio line. With a different design, its electrical circuit and design almost did not change. On the basis of the Araz radio line of the 1953 model for the expansion of the product range, the Baku-55 receiver was created, which is similar in design to the Araz radio line.
