Black-and-white television receiver "Quant".
Black and white televisionsDomesticThe television receiver of the black-and-white image "Quant" in 1968 was produced by the Leningrad plant named after Kozitsky. The lamp-semiconductor TV Kvant replaced the TV Evening. It was created based on it. The Kvant TV uses a 59LK2B kinescope. It was now the same as the TV `` Evening '' in its time, a qualitatively new television receiver. First of all, because the Kozitsky Leningrad Radio Plant continued to solve the problem of replacing radio tubes with transistors, as well as a kinescope with a much larger screen size. The Kvant TV has 8 tubes and 21 transistors. Power consumption, in comparison with similar lamp models, decreased to 130 W, in lamp or lamp-semiconductor models of the 2nd class, it was 180 W. In the Kvant TV, the automatic brightness control circuit has been improved depending on external lighting, a new high-frequency and sensitive program switch unit PTK-10B with increased protection against heterodyne radiation has been used, and the line scan unit has been improved. Whether it was a unified TV, it was produced experimentally or serially, up to what years, its technical parameters, such data as his photo, could not be found.
