Electric lamp network lamp "EP-3".
Electric players and tube electrophonesDomesticIn 1950, the network tube electrogramophone EP-3 was produced by the Moscow Radio Products Plant No. 3. The EP-3 electrogramphone (electrophone) in the Moscow Polytechnic Museum is called an electric player and is designed to play gramophone records at a speed of 78 rpm. There is no other information on this model. It is unknown whether it was a production model or was made in one copy. It is known that this device was donated by the staff of the plant in honor of some kind of anniversary to Joseph Vissarionovich Stalin and was found among personal belongings after his death. In the fall of 2002, the EP-3 electrogramophone is an exhibit of the Polytechnic Museum of the city of Moscow. Judging by the plate in the PM, the device could receive radio transmissions. Perhaps just a wire broadcast.
