The electric player "EGK-1" was developed in 1933 by the Central Radio Laboratory of WESO and was produced by the department of consumer goods of the plant it. Kazitsky. Here is a description of the model in Radiofront magazine No. 4 for 1934: The model is the first electro-microphone that our industry issued. A gramophone is a combined type, as using it, it is possible to carry out both acoustic (membrane and punop) and electric (adapter, amplifier and gramophone) reproduction of gramophone records. The gramophone does not have amplification and a loudspeaker and must be connected (of course, if electrical repetition is desired) to any low-frequency amplifier or receiver with the appropriate input for the adapter. The disk rotates a small asynchronous motor with a short-circuited anchor. The rotation from the motor to the disk spindle for the plates is transmitted by means of a rubber pulley. The number of revolutions of the disk is adjusted by means of a cone, which changes the transmission ratio of the motor and spindle pulleys. Gramophone is designed to be included only in the AC network.
