Radiola network lamp `` Sirius-308 ''.

Network tube radiosDomesticRadiola network lamp "Sirius-308" since 1970 was produced by the Izhevsk radio plant. The block tube radiola of the III class "Cirius-308" is developed on the basis of the serial radio tape "Cirius-5". This is the first class III radio, structurally made in the form of two separate units: a radio receiver and an EPU with an acoustic system. The radio receiver of the radio is designed to receive transmissions of local and long-distance radio stations with AM in the ranges DV 2000 ... 735 m, SV 571 ... 187 m, KV 75 ... 25 m, and VHF 5.56 ... 4.11 m Receiver sensitivity in the ranges DV, SV - 120 µV, HF - 200 µV, VHF - 20 µV. IF AM path - 465 kHz, FM path - 6.5 MHz. The selectivity of the receiver along the AM path with detuning by 10 kHz is 30 dB. In FM, the averaged slope of the slopes of the resonance characteristic in the signal attenuation range from 6 to 26 dB is 0.17 dB / kHz. Rated output power 0.5, maximum 1 W, frequency range 125 ... 7100 Hz. Sensitivity from the pickup sockets 100 mV. The background level from the ULF input is 40 dB. The limits of the timbre of the highest sound frequencies relative to 1000 Hz, not less than 9 dB. The EPU of the radio is designed to play ordinary and long-playing gramophone records at speeds: 78, 45 and 33 rpm. The radio is powered by an alternating current. Power consumption when receiving radio is 50 W, when the EPU is in operation - 65 W. The dimensions of the receiver are 158x326x420 mm, its weight is 6.8 kg. EPU with AC 158x290x420 mm, weight 6.4 kg. Radiola is rare, about 7 thousand copies were produced and in the same 1970 the release of the model was completed.
