Since 1965, Vaf-Radio"™s mains lamp network has been produced by the Riga State Electrotechnical Plant VEF. At the beginning of 1965, the Riga factory VEF began the serial production of radiometers of the brand '' VEF-Radio '', another name '' VEF-Radio-65 ''. Radiol consists of an 8-tube superheterodyne receiver of the 1st class and a 3-speed electro-playing device III-EPU-20 or II-EPU-40. The radio receiver is designed for receiving radio stations in the range of long, medium, short and ultrashort waves, the HF band is divided into two sub-bands. An internal rotary ferrite antenna was used for receiving in the DV and SV bands, and an internal dipole in VHF. The radiole has a smooth tone control, separately for high and low frequencies. The schematic diagram of the radiofoil is similar to the radiofrequency '' Rigonda-mono '' circuit with the exception of small changes in the values "‹"‹of the elements in the KSDV-PCh and BP unit and is distinguished by the external design of the case, which can be floor-standing and desktop. The speaker consists of a loudspeaker 4GD-4. The dimensions of the radio are 740x336x320 mm, weight 21 kg. Ranges: LW 150 ... 408 kHz. MW 525 ... 1605 kHz. HF-1 3.95 ... 7.4 MHz. HF-2 9.1 ... 12 MHz and VHF 65.8 ... 73 MHz. Sensitivity with external antenna in the ranges of DV, SV, KV 50 mV, in the range of VHF 5 mV. Sensitivity with an internal magnetic antenna in the ranges of LW, MW 1.5 mV / m. In the AM, IF 465 kHz path, the bandwidth at the attenuation of the signal is 6 dB in the "narrow band" position at 5 kHz, the wide band at 11 kHz and in the position local reception at 15 kHz. In the path of the FM, IF 6.5 MHz, the bandwidth of 150 kHz. Selection on the AM path 60 dB. AGC provides a change in the output signal by 11 dB when changing the input by 40 dB. The maximum output power is 3.5 W, the range of reproducible sound frequencies of the AM path is 80 ... 6000 Hz, FM 80 ... 12000 Hz, recording 80..10000 Hz. Sensitivity from pickup sockets 200 mV. The control unit is equipped with an automatic switch and a microlift, designed for playing records at speeds of 78, 45 and 33 rpm. Radiols are powered from the mains.Power consumption when receiving 60 watts, and when listening to records 75 watts.
