Network tube radio receiver '' VEF SUPER M-517 '' (VEFSUPER M-517).
Tube radios.DomesticThe VEF SUPER M-517 network tube radio receiver (VEFSUPER M-517) has been produced by the VEF Electrotechnical Plant since 1940. The electrical circuit of the receiver has been revised at least four times. These are historical and political nuances. The radio was produced on German and Soviet lamps. First development at the end of 1940 on red Philips lamps. Technical parameters. Ranges: LW: 150 ... 450 kHz; MW: 518 ... 1520 kHz; HF: 5.85 ... 18.4 MHz There was an option for Norway, with an additional HF range for fishermen. Powered by AC 110, 127 or 220 V. Raimonds writes: I have a version of a radio set on Soviet lamps. It has four knobs. The point is that in one period it became a shortage of double knobs and the left knob was made as a tone control with stepped adjustment. It was not yet possible to establish the release date of the receiver (radio) with a gramophone, but probably still before the war. The radio "VEF SUPER M-517" is not the original source with his family. The first `` round-scale '' receiver was developed in July 1938 on American lamps of types: 6A8G, 6B8G, 6E5G, 6K6G, 1-V. The last `` round scale '' made immediately after the war and with minor modifications to the electrical circuit of the VEF SUPER M-517 model became the VEF SUPER M-557 receiver. In addition to the operating frequency ranges, the rest of the technical parameters of the radio receiver, respectively, coincide with the data of the VEF SUPER M-517 radio receiver.
