Black and white televisionsDomesticThe television receiver of the black-and-white image "Ogonyok-2" has been producing Lviv TVZ since July 1967. The unified tube-semiconductor television receiver of the second class "Ogonyok-2", type ULPPT-47-1, is designed to receive television programs in black and white on any of the 12 channels of the MW range. It uses a 47LK2B kinescope (47LK2BS) with a beam deflection angle of 110 ° and an image size of 385x305 mm. The TV set is assembled on 14 radio tubes and 23 semiconductor devices. Transistors are used in the amplification path of intermediate frequencies and low-frequency sound channel. The sensitivity of the TV is standard for all unified second class models and is equal to 50 μV. The nominal output power of the soundtrack channel is 1.5 W. The range of reproducible frequencies is 100 ... 10000 Hz. Power consumption from the network is 180 W. The dimensions of the TV are 590x460x330 mm. Weight 27 kg. The TV was produced until 1971 in several versions of the external design, having undergone three "modernizations" in 1968, 1969 and 1970. The design and electrical circuit did not change, it was the same ULPPT-47-1, but with the addition of a number in the name, for example "Ogonyok-2-1", "Ogonyok-2-2", "Ogonyok-2-3". According to this design and design, the plant produced "Electron-2" TV sets, but on a 59LK2B type kinescope.
