The VEF-Radio radio scheme has practically no fundamental differences from the radio scheme. Radiola network lamp ''Vef-Radio'' Schemes for lamp radiola vef

Radiola network lamp "Vef-Radio" since 1965 was produced by the Riga State Electrotechnical Plant "VEF". At the beginning of 1965, the VEF Riga plant began serial production of the VEF-Radio brand radio, another name is VEF-Radio-65. The radiola consists of an 8-tube superheterodyne receiver of the 1st class and a 3-speed electric player III-EPU-20 or II-EPU-40. The radio receiver is designed to receive radio stations in the ranges of long, medium, short and ultrashort waves, the HF range is divided into two sub-bands. For reception in the ranges of LW, SV, an internal rotary ferrite antenna is used, and in VHF, an internal dipole. The radiol has a smooth tone control, separately for treble and bass. The circuit diagram of the radiola is similar to the circuit of the "Rigonda-mono" radiola, with the exception of minor changes in the values ​​​​of the elements in the KSDV-FC and PSU block and differs in the external design of the case, which can be floor and desktop. The speaker consists of a loudspeaker 4GD-4. Radiola dimensions 740x336x320 mm, weight 21 kg. Ranges: DV 150...408 KHz. CB 525...1605 kHz. KV-1 3.95 ... 7.4 MHz. KV-2 9.1 ... 12 MHz and VHF 65.8 ... 73 MHz. Sensitivity with an external antenna in the ranges of LW, MW, HF 50 µV, in the VHF range 5 µV. Sensitivity with an internal magnetic antenna in the ranges of LW, SV 1.5 mV / m. In the AM path, 465 kHz IF, 6 dB attenuation bandwidth at 5 kHz narrow band, 11 kHz wide band, and 15 kHz local. In the FM path, IF 6.5 MHz, bandwidth 150 kHz. AM selectivity 60 dB. AGC provides an output signal change of 11 dB for a 40 dB change in input. The maximum output power is 3.5 W, the range of reproducible audio frequencies is AM tract 80 ... 6000 Hz, FM 80 ... 12000 Hz, recordings 80..10000 Hz. Sensitivity from pickup jacks 200 mV. The EPU is equipped with an auto switch and a micro-lift, designed to play records at speeds of 78, 45 and 33 rpm. The radiola is powered from the mains. Power consumption when receiving 60 watts, and when listening to a recording 75 watts.

Manufacturer / company / country: Riga State Electrotechnical Plant VEF

Production year: 1965

The Riga State Electrotechnical Plant "VEF" was the largest electrotechnical enterprise in Latvia during the Soviet era. VEF radio receivers became the face of the plant. At the international exhibitions of 1935 in Brussels and 1937 in Paris, devices under the VEF brand were awarded the "Grand Prix". The plant produced such a quantity radios that the local market was not able to absorb them, the export of radios to other countries was started.Starting from 1935, VEF opened sales offices in Tallinn, Kaunas, Helsinki, Oslo, Zurich and London.Before World War II, VEF exported 8000 radio receivers per year.

Characteristics:"VEF-Radio", another name is "VEF-Radio-65". The radio receiver is designed to receive radio stations in the ranges of long, medium, short and ultrashort waves, the HF range is divided into 2 sub-bands. The radiol has a smooth tone control, separately for higher and lower frequencies. Weight - 22 kg. Legs add 570mm of height.
