Sansui 999

This is a pre-main amplifier that is the highest grade model of Sansui's PB series and an upgraded version of AU d, sansui 999. Sansui 999 for more faithful sound reproduction, it was developed by accumulating thorough hearing tests. The main amplifier section uses a 2-stage differential amplifier circuit and a fully connected system with two power supplies plus and minus without an output capacitor. This makes NFB uniform from the ultra-high band to the ultra-low band and improves various characteristics.

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 to deliver a full watts 4 ohms in music power output with unprecedented tone quality. 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.

Not sure if this runs negative voltage so the question is Can't go wrong.

Aiming for more faithful sound reproduction, it was developed by accumulating thorough hearing tests. The main amplifier section uses a 2-stage differential amplifier circuit and a fully connected system with two power supplies plus and minus without an output capacitor. This makes NFB uniform from the ultra-high band to the ultra-low band and improves various characteristics. The equalizer stage uses a 3-stage E-E NF type PNP silicon transistor with low noise, and achieves low noise, low distortion, wide dynamic range and high stability. A direct-coupled circuit is used as much as possible for the amplifier circuit, and a Mylar capacitor is used as much as possible for the necessary part of the coupling capacitor. Electrolytic capacitors with large phase distortion in the high frequency range and poor transmission characteristics are eliminated.

Good thing is it has been gone through, adjusted and cleaned. Electrolytic capacitors with large phase distortion in the high frequency range and poor transmission characteristics are eliminated. One would be correct. You must log in or register to reply here. Daunia 70 Lunatic Member. What terminal goes to chassis on the filter caps? Replies 21 Views 1K. I know it is hard to opine but does the description for the work done sound appropriate? I have both the AU and AU Current visitors Billboard Trophies. Replacing the filter caps on the will certainly NOT be to the detriment of sound quality.

If you have the chance to give it a good listen, I would do so. I like the A's looks It's considerable heft and lack of cheap plastic! Jan 9, Hyperion. At that price not a bad amp to go with. New posts Latest activity. The should be no different in terms of its abilities, so I expect you'll find it works with quite a lot of brands. Any opinions on this model? Even looking within the sansui brand at that time, more money typically got you more power and a couple of features, not a better sounding amp. As a professional musician I peeled off literally hundreds of songs using that old setup. Hello all, Well ive decided to take a shot at some vintage kit. Moderators online.
