From the middle of 1956, the radio receiver and the Oka radio network lamp began to be produced at plant No. 672 of the NKEP, MMSS (subsequently Kaluga Electromechanical Plant). On the basis of the Baltika receiver, a radio receiver and an Oka radio are developed and are being produced. Radiola "Oka" is designed to play regular and long-playing records. Such shortcomings of the Baltika receiver are eliminated in the radio channel, as for the pickup, the radio receiver is supposed to be switched off, a capacitor is included in the antenna circuit, and a subscriber loudspeaker with an operating voltage of 30 V is used as an external loudspeaker. To improve the sound quality in the radio and the receiver, the use of 2 loudspeakers ZGD-2 is envisaged. The tests of prototypes of the radio receiver and the Oka radio have shown that the sound quality when receiving radio stations and playing the recording is satisfactory. According to the wiring diagram and quality indicators, the radio receiver and the Oka radio is not much different from the VEF-Accord radio receiver. The radio receiver and Oka radio were developed at the beginning of 1956 in the design bureau of the Riga State Electrotechnical Plant VEF.
