The television receiver of the black-and-white image "Kvant" in 1968 produced the Leningrad Kozitsky Plant. Lamp-semiconductor TV "Quantum" has replaced the TV "Evening". It was created on its basis. The TV "Kvant" used a kinescope type 59LK2B. It was now the same as in its time and the TV "Evening" a qualitatively new television receiver. First of all, because the Leningrad Radio Plant named after Kozitsky continued to solve the problem of replacing radio tubes with transistors, as well as with a kinescope with a much larger screen size. The TV "Kvant" has 8 radio tubes and 21 transistors. Power consumption, as compared with similar lamp models, decreased to 130 W; in lamp or lamp-semiconductor models of the 2nd class, it was 180 W. The Kvant TV has improved the automatic brightness adjustment scheme depending on the ambient light, applied a new high-frequency and sensitive PTK-10B program switch block with enhanced protection from heterodyne radiations, improved horizontal scanning unit Whether it was a unified TV, was produced experimentally or serially, until what years, its technical parameters, such data as its photo could not be found.
