Amplifier full "Pulsar U-001-stereo" since 1984 produced Ulyanovsk mechanical plant. The amplifier is designed to amplify and switch signals from various sources. It provides timbre adjustment on the LF, MF and HF, stepwise loudness attenuation by 20 dB, switchable infra-low frequency filter. Two pairs of speakers and stereo phones or two tape recorders can be connected to the amplifier. Each channel provides electronic protection of output transistors against short circuit in the load. On the amplifier case there are sockets installed through which two radio devices with a total power up to 200 watts can be connected to the network. Rated output power 2x35 W (4 ohms). The total harmonic coefficient of 0.15%. The range of reproducible sound frequencies is 20 ... 25000 Hz. Signal-to-noise ratio -85 dB. Transient attenuation between -48 dB channels. The limits of tone adjustment on the LF, MF and HF, respectively ± 12, ± 10, ± 15 dB. The dimensions of the amplifier are 460x90x360 mm. Its weight is 10 kg. The price is 300 rubles. Since 1988, another plant produced a similar, but with a few differences in the design amplifier '' Idol U-001-stereo ''.
