The television receiver of the black-and-white image "Spark-2" from July 1967 produced the Lvov TVZ. The unified tube-semiconductor television receiver of the second class "Spark-2" type ULPPT-47-1 is designed to receive television programs in black and white on any of the 12 channels of the MV range. It used a kinescope 47LK2B (47LK2BS) with a beam deflection angle of 110 ° and an image size of 385x305 mm. The TV is assembled on 14 radio tubes and 23 semiconductor devices. Transistors are applied in the amplification path of intermediate frequencies and low-frequency sound channel. The sensitivity of the TV is standard for all unified models of the second class and is 50 µV. Sound output channel rated power 1.5 watts. Frequency range 100 ... 10000 Hz. Power consumption 180 watts. The dimensions of the TV 590x460x330 mm. Weight 27 kg. The TV was produced before 1971 in several variants of external design after undergoing three "modernization" in 1968, 1969 and 1970. The design and electrical circuit did not change, it was the same ULPPT-47-1, but with the addition in the name of the number, for example, "Spark-2-1", "Spark-2-2", "Spark-2-3". The plant produced Electron-2 TV sets for this design and design, but on a 59LK2B type kinescope.
