Fenomen Mz 744 Telefunken radio receiver

The Fenomen Mz 744 is a tabletop vacuum-tube radio, with a mains AC power supply. It was launched on the market in the 1937/1938 season by Krajowe Towarzystwo Telefunken sp. z o.o. – the Polish branch of the German radio technology corporation. The Warsaw branch of Telefunken manufactured radios under a foreign licence, but they were designed in Poland and adapted to local technical conditions. The Fenomen is a four-circuit superheterodyne receiver built on iron cores, equipped with four vacuum tubes and a reaction detector. The Fenomen was marketed in three versions; apart from the Mz 744, they were the Mu 744 with DC power supply and the battery-powered Mb 713. After 1935, a horizontal layout of radio receivers became popular and the Fenomen was designed in accordance with that trend. Manufacturer: Krajowe Towarzystwo Telefunken Sp. z o.o., 1938 Inv.
