This unit is rebuild (I have to add some photos from inside) The cappacitors are replaced with Nichicion and some partas, resistors, small transistors are replaced with new onece, THE MAIN TRANSISTORS ARE OF COURSE ALL ORIGINAL. Visualy is very good, technicaly it’s exelent! It sounds more natural and analog from the AU 9500, it’s closer to AU 70 than to AU 9500. I’m askig for more than usual for this one becouse I invest money to rebulld it and now it will last much more than the one originaly from 1970 and it will work after 20 more years. I’t will be packed very very good and send.
DescriptionThe AU-999 is the most advanced professional control amplifier ever manufactured by Sansui.Designed specifically for the ardent audiophile, it features the refined dull black panels common to all AU series professional control amplifiers from Sansui.The pre-amplifier section is constructed of carefully selected low-noise PNP silicon transistors, while the power amplifier section features direct-coupled circuits specially developed with the improvement of tonal quality in mind.Together, they permit the AU-999 to deliver a full 180 watts (4 ohms) in music power output with unprecedented tone quality.The AU-999 is lavishly endowed with accessory circuits.These include a tone selector circuit, an improved form of the triple tone control circuit that offers a choice in selecting the critical frequencies of tone control; a speaker selector which permits connecting three sets of speaker systems; a balance check switch which simplifies the job of adjusting for optimum balance of the right and left channel sound volumes; facilities to connect two phonographs and two tape decks, and a tape reprint circuit.Special provisions have also been made to permit the amplifier to be built up into an electronic crossover stereo system and permit comparing such a system with a standard stereo set-up.SpecificationsPower output: 50 watts per channel into 8 (stereo)Frequency response: 20Hz to 70kHzTotal harmonic distortion: 0.4%Damping factor: 45Input sensitivity: 3mV (mic), 2mV (MM), 200mV (DIN), 200mV (line)Signal to noise ratio: 80dB (mic), 80dB (MM), 85dB (line)Output: 200mV (line), 30mV (DIN)Speaker load impedance: 4 to 16Semiconductors: 41 x transistors, 16 x diodes, 2 x triacDimensions: 18-1/8 x 6-1/8 x 12-1/2 inchesWeight: 38.5lbs
