Transistor network electrophone '' Vega-104-stereo ''.
Electric record players and electrophones on semiconductorsDomesticThe network transistor microphone "Vega-104-stereo" has been produced by the Berdsk Radio Plant since 1976. The "Vega-104-stereo" stereophonic desktop microphone of the 1st class since 1976 has been produced in the design as in the main photo on the left. Electrophone is designed to play both mono and stereo phonograph records of any format. The electrophone was developed on the basis of the Arctur-002-stereo UCU. It differs from the Vega-103-stereo microphone in design, the presence of low, medium and high frequency filters, the use of the new II-EPU-62S, instead of the II-EPU-52S, the presence of an output level and overload indicator. EPU 2-speed with adjustment of the disk rotation frequency and adjustment of the cartridge weight. The EPU has a microlift and hitchhiking with automatic return of the pickup to the rack. In the EPU there is an electromagnetic head GZM-105. Three high-speed EPUs were also installed. AC type 15AC-1, each of which contains two heads of type 6GD-6 and one 6GD-11. The nominal output power of the microphone is 2x15 W, with a harmonic factor of 0.7%. The range of effectively reproduced sound frequencies is 30 ... 20,000 Hz. The relative noise level is 31 dB, the knock coefficient is 0.15%. Power consumption 100 watts. The dimensions of the microphone are 592x360x200 mm, the speaker is 400x240x170 mm, the weight is 17 and 12 kg. Price 257 rubles. Since 1978, a modernized, familiar in design, Vega-104-stereo electrophone has been produced. The AC was used here 15AS-404, which reproduced the frequency band 63 ... 18000 Hz. Some `` excesses '' were removed, the rated output power was reduced to 2x10 watts. The dimensions have changed to 465x385x200 mm, the AC up to 420x250x190 mm, and the power consumption has been reduced to 80 W.
