I will continue my story about "folk radio" in the USSR ... A popular and fairly simple and cheap radio record -47 was still quite expensive for the poor after the inmate of the population of the USSR. The population was in demand even simpler and cheaper radio. And in 1949 two models of the simplest three lamp superheteradins, made on a reflex scheme appeared at once. These were the radio receivers Москвич Б (Moskvich B) and ARZ-49. In both receivers, the autotransformer was used in the power supply, and instead of the lamp kenotron selenium rectifier.Москвич Б ( Moskvich B) had a plastic case and was considered the cheapest in the USSR by a tube superheterodyne type radio receiver. In various modifications, these radios were released by the end of the 1950's and were the most popular and popular radio receivers in the USSR at that time.
Москвич Б (Moskvich B)
Very quickly it turned out that selenium rectifier is a very precarious element and since 1951 it was replaced by a tube kenotron. Thus both models became 4-lampic superheterodynamics.
The view on the chassis is joyfully Moskvich B of the second modification in the kenotron instead of the selenium rectifier.
