The transistor "Arctur-003 stereo" network transistor battery from the 1st quarter of 1977 was produced by the Berd Radio Plant. The stereophonic elec- tronic of the highest complexity group "Arctur-003-stereo" is designed to play recordings from mono or stereo records with disc rotation speeds of 33 and 45 rpm. The Arctur-003 stereo electrophone has been developed based on the Arctur-001-stereo serial amplifying and switching device. In addition to the loudness and timbre controls for the low and high frequencies, there are switched low and high frequency switching filters with which you can narrow, expand and select the reproducible frequency band, the active presence filter, and also the dial gauges for the output levels of both amplifiers stereo channels. In the new electrofon, the EDA G-600 V (Poland) or the like with a magnetic pickup head is used. The frequency of rotation of the disk is set by the built-in strobe. The microphone is equipped with two 25-type two-way loudspeakers. The nominal reproducible frequency range for sound pressure is 40 ... 20000 Hz. Sinusoidal rated output power 25 watts. Background voltage level at a sinusoidal output power -50 dB. Knock factor of EPU ± 0.1%. The power consumed from the mains is 150 watts. The dimensions of the electric player 615x385x200 mm, one speaker - 480x285x250 mm. The weight of the electric player with the amplifier LF - 22 kg.
