The stationary transistor radio "Estonia-007-stereo" was developed at the beginning of 1975 by the Tallinn factory "Punane-RET". The model used electro-playing device IEPU-73S with a magnetic pickup. The radio is designed to receive mono and stereo programs in the VHF-FM range. Low-frequency amplifiers are located in radio speakers. The rated output power of the radio is 2x25 watts. The range of reproducible frequencies of sound pressure during EPU operation and reception in VHF-FM is 40 ... 15000 Hz. Nonlinear distortion coefficient not more than 0.7%. For some reason, the radio wave did not go into mass production. Information about the radio in the magazine Radio No. 9 for 1975.
