The transistor "VEGA-104-stereo" network transistor since 1976 has been producing the Berdsky Radio Factory. The stereo desktop class 1 "Vega-104-stereo" desktop audio was produced in 1976 as in the main photo on the left. Electrophone is designed to play both mono and stereo records of any format. The electric phone was developed on the basis of the Arctur-002-stereo UCU. It differs from the "Vega-103-stereo" electrophone by its design, the presence of low, mid and high frequency filters, the use of a new II-EPU-62C, instead of II-EPU-52C, the presence of an output level and overload indicator. EPU 2-speed with adjustment of the frequency of rotation of the disk and the weight of the pickup. There is a microlift and auto-stop with automatic return of the pickup on the stand. In the EPU is an electromagnetic head GZM-105. Set and three speed EPU. AU 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 ratio of 0.7%. The range of effectively reproduced sound frequencies is 30 ... 20000 Hz. The relative level of interference is 31 dB, the detonation coefficient is 0.15%. Power consumption 100 watts. The dimensions of the phone are 592x360x200 mm, the speakers - 400x240x170 mm, weight 17 and 12 kg. Price 257 rubles. Since 1978, the modernized Vega-104-stereo electronic microphone has been produced. The AC here used 15АС-404, which reproduced the frequency band 63 ... 18000 Hz. Some "excesses" were removed, the nominal output power was reduced to 2x10 watts. Dimensions have changed to 465x385x200 mm, speakers to 420x250x190 mm, and power consumption is reduced to 80 watts.
