Since 1945, the network vacuum lamp VEF M-1357 has been produced by the Riga factory VEF. The experimental workshop of the VEF plant immediately after the end of the war produced a small experimental batch of receivers from the VEF M-1357. The design of the receiver was developed by the factory before the war. In the first embodiment, the receiver had, in addition to the smooth and push-button tuning to the radio stations selected in advance by the listener. After the end of the war, the receiver was already launched without limited push-button tuning, but the automatic frequency control, push-button switching of the toner correction and the expander were saved. Radio VEF M-1357 was created on the basis of the radio VEF Luxus M1307, developed in early 1940. In the design documentation, the original receiver was called '' VEF Luxus M1357 ''. The radio designer Alberts Madisons who worked at the plant since its foundation took part in the development of both models. The radio receiver contains 14 lamps (2 kenotrons are connected in parallel), it has an APSG and an expander that expands the dynamic range of the reception. The following lamps are installed in the model: 6К8, 6К7 (3), 6Ж7, 6Ð¥6 (2), 6Ð 7, 6Ð7, 6П6 (2), 6Е5, 5Ц4С (2). The ranges of frequencies and waves received by the radio receiver: LW - 150 ... 430 kHz, CB - 520 ... 1500 kHz. KB1 4.1 ... 10.5 MHz (28.6 ... 73.2 m). КВ2 - 9.2 ... 23 MHz (13 ... 32.6 m). KV3 - 15.03 ... 15.4 MHz (19.48 ... 19.96 m) IF 465 kHz. The nominal output power of the radio amplifier is 12 W, the maximum 15 W consumed from the mains power is 200 W. The first photo shows the base receiver VEF M-1357, photos of the chassis too. Receivers are almost identical on the chassis except the button settings.
