Radiola network lamp "Rigonda-102".

Network tube radiosDomesticRadiola network lamp "Rigonda-102" since 1970 has been produced by the Riga Radio Plant named after A.S. Popov. The monophonic network radio receiver of the 1st class Rigonda-102 has replaced the radio receiver Rigonda-Mono. Compared to the previous one, it provides more confident reception and better sound quality. In the radio "Rigonda-102", the output power is almost 2 times increased, the sensitivity of the tuning indicator is 2-3 times higher. Improved AGC. A separate tape recorder key has been introduced, which allows recording on a magnetic tape when receiving and playing a gramophone. Reliability was increased by replacing the ABC-80x260 rectifier, which operated in the limit mode, with the assembly of KTs-401B. Improved design of the radio. In other respects, the radio is similar to the previous model, the Rigonda-mono radio. The price of a new radio is 150 rubles. The radio receiver `` Rigonda-102 '' is designed to receive transmissions from radio stations operating in the DV ranges - 150 ... 408 kHz (200 ... 735.3 m); SV - 525 ... 1605 kHz (571.4 ... 186.9 m) two shortwave KV-2 3.95 ... 7.4 MHz (75.9 ... 40.5 m), KB- 1 9.36 ... 12.1 MHz (32.0 ... 24.7 m), and VHF - 65.8 ... 73 MHz (4.56 ... 4.11 m) waves. Receiver sensitivity in DV, MW and HF ranges 20 ... 60 μV, in VHF-FM range 3 ... 6 μV. Selectivity on the adjacent channel in the AM path - 66 dB. The nominal output power of the radio is 3 W, the maximum is 7 ... 10 W. The radio acoustic system consists of four loudspeakers: two 4GD-28 (later replaced by one 4GD-35) and two 1GD-28 (later 1GD-36). Sound pressure at rated power 1.6 ... 1.8 N / m. The range of effectively reproduced audio frequencies for the AM path is 60 ... 6000 Hz, FM - 60 ... 12000 Hz. The radio is equipped with a three-speed EPU type II-EPU-40 (later II-EPU-50), designed to reproduce records from conventional and LP records. The radio is powered by a 220 or 127 V network, its dimensions without legs are 640x355x550 mm, weight is 24 kg. A set of radio tubes in the radio: 6N3P, 6I1P, 6K4P (2), 6X2P, 6N2P, 6P14P (2), 6E1P. The radio tape Rigonda-102 was supposed to be released since 1968, but for various reasons, the release was postponed. Since the beginning of the release of the radio, its design was closer to the base model, then the radio fabric was gradually replaced, the frame of the tuning scale changed, and one broadband loudspeaker was removed from the radio speaker.
