Black and white televisionsDomesticThe "Luch" black-and-white television receiver has been produced by the Moscow Radio Engineering Plant since 1955. The "Luch-1" TV (1st model) is one of the upgrades of the "North" TV. The new TV set operates in the first three channels and can receive local VHF-FM radio stations, as well as reproduce a recording from an external EPU. It is mounted on a metal chassis placed in a wooden case with imitation of precious woods with dimensions of 630x480x425 mm. The weight of the device is 38 kg. The main control knobs are displayed on the front panel, which, in addition to the range switch, are combined in pairs. Under the shutter, there are knobs for line frequency, frame rate, vertical size and a scale used for TV and FM reception. The scale is also an indicator of programs. When receiving TV, the scale is less illuminated, and the VHF-FM is more. When watching programs, after setting, the shutter is closed. On the rear of the chassis, there are auxiliary knobs of the horizontal size and non-linearity of the pickup socket, antennas for long and short reception, as well as a voltage switch and a fuse. The back of the TV is covered with a cardboard wall with cutouts for access to sockets, control knobs and fuses. There is a lock on it that protects against voltage exposure. The TV is powered by 110, 127 or 220 V. Power consumption 200/100 W. It uses 17 radio tubes, a 31LK2B kinescope and 2 speakers of 1 Watt each. The sensitivity of the TV is 600 ... 1000 μV. In many reference books, the Luch-1 television receiver is often referred to as Luch. Since the 1st quarter of 1957, the plant has been producing the modernized Luch-2 TV, which differs only in its external design, which is copied from the Ekran model.
