Radiola network lamp "Sirius-308" since 1970 was produced by the Izhevsk radio plant. ,86e6f450b8cc469628ba70bf2947b049The block tube radiogram of the III class "Cirius-308" is developed on the basis of the serial radio "Cirius-5". ,86e6f450b8cc469628ba70bf2947b049This 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. ,86e6f450b8cc469628ba70bf2947b049The 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 ,86e6f450b8cc469628ba70bf2947b049Receiver sensitivity in the ranges DV, SV - 120 µV, HF - 200 µV, VHF - 20 µV. ,86e6f450b8cc469628ba70bf2947b049IF AM path - 465 kHz, FM path - 6.5 MHz. ,86e6f450b8cc469628ba70bf2947b049The selectivity of the receiver along the AM path with detuning by 10 kHz is 30 dB. ,86e6f450b8cc469628ba70bf2947b049In 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. ,86e6f450b8cc469628ba70bf2947b049Rated output power 0.5, maximum 1 W, frequency range 125 ... 7100 Hz. ,86e6f450b8cc469628ba70bf2947b049Sensitivity from the pickup jacks 100 mV. ,86e6f450b8cc469628ba70bf2947b049The background level from the ULF input is 40 dB. ,86e6f450b8cc469628ba70bf2947b049The limits of the timbre of the highest sound frequencies relative to 1000 Hz, not less than 9 dB. ,86e6f450b8cc469628ba70bf2947b049The EPU of the radio is designed to play ordinary and long-playing gramophone records at a speed of 78, 45 and 33 rpm. ,86e6f450b8cc469628ba70bf2947b049The radio is powered by an alternating current of 127 or 220 V. Power consumption when receiving radio is 50 watts, when the EPU is operating - 65 watts. ,86e6f450b8cc469628ba70bf2947b049The dimensions of the radio are 158x326x420 mm, its weight is 6.8 kg. ,86e6f450b8cc469628ba70bf2947b049EPU with AC - 158x290x420 mm, weight 6.4 kg. ,86e6f450b8cc469628ba70bf2947b049Radiola is rare, about seven thousand copies were produced and in the same 1970 the release of the model was completed.,86e6f450b8cc469628ba70bf2947b049,null,ru,null,null,null,null
