[RadioSvit]

Hello John. I have never met VEF156 and have not even heard of the existence of such a model. Perhaps you are mistaken with the model index. But there was a VEF Lux (RK-156) model from 1956. If you are asking about this radio, then it usually had a monophonic push-pull amplifier and 4 speakers connected in a 3D scheme. That is, two front broadband plus two side ones for reproducing mid and high frequencies, connected via a capacitor. I had such a radio and it had excellent sound. But it was monophonic. The first stereophonic radios appeared in the USSR only in 1962, but these were also small-scale batches without stereo detectors, that is, only the amplifier and speakers were stereophonic, but not the FM radio receiver. Fully stereophonic radios appeared only in 1965-67. These were Rigonda Stereo and Symphony Stereo. By the way, the principle of operation of Soviet stereo detectors was very different from European ones, and therefore such radios were not suitable for receiving stereo programs in Europe and the USA. For Europe and the USA, radio receivers adapted to the Western standard were manufactured with a different frequency range (88-108 MHz) and a Western stereo signal demodulation system, for example, Rigonda Bolshoi.
