Russian tube 6P45S (6П45C) was in the past used in the TV receivers. At the time, when this tube was designed, the russian ingenieurs have used the Tele EL509 as a template. There are some small differences, but what really matters is the fact that the 6P45S and the EL509 are directly replaceable. Minimum of 5000 operating hours. New old stock tubes, directly from the factory packing (please see the gallery). Years of production: 1987 and 1991.
