The television receiver of the black-and-white image "Beam" since 1955 let out the Moscow radio engineering plant. Television '' Beam-1 '', (1st model) is one of the upgrades of the TV "North". The new TV operates in the first three channels and can receive local VHF-FM radio stations, as well as play back recordings from 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 front panel displays the main control knobs, which, except for the range selector, are combined in pairs. Under the curtain, there are knobs of line frequency, frame rate, vertical size and scale used when receiving TV and FM. The scale is also an indicator of programs. When receiving a TV scale is lit less, and VHF-FM more. When viewing programs, after setting, the curtain is closed. Auxiliary handles of horizontal size and non-linearity of the pickup socket, antennas for far and close reception, as well as a voltage switch and a fuse are placed on the chassis behind. The rear wall of the TV is covered with a cardboard wall with cutouts for access to the sockets, control knobs and fuses. It has a lock that protects against voltage. The TV is powered by 110, 127 or 220 volts. Power consumption 200/100 watts. It used 17 radio tubes, kinescope 31LK2B and 2 speakers of 1 watt each. The sensitivity of the TV 600 ... 1000 µV. In many references, the television receiver '' Ray-1 '' is often referred to as '' Ray ''. From I quarter of 1957, the plant produced an upgraded TV '' Beam-2 '', differing only in its external design, which is copied from the '' Screen '' model.
