Sansui 999

This is a pre-main sansui 999 that is the highest grade model of Sansui's PB series and an upgraded version of AU d, sansui 999. 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, sansui 999.

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.

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. 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. Can be used independently by separating the pre-main part. Two tape decks can be used simultaneously and a TapetoTape reprint switch is mounted. The wood case was sold separately.

I humbly ask thee one question: is the Sansui AU a quality, clear sounding amp? I am na audiophile but Sansui au is a fantastic Amp Reviewed Apr 15th, by mistergsf. In the Netherlands, this unit will do definately a lot more if it looks good and no knobs missing , it seems dead or alive does not make much of a difference, my guess many times the ones liking these units are techs themselves.

If it has really been serviced and some caps replaced it could be worth a bit more, depending on physical condition. Jul 3, nosirrah. Wow, i had no idea it was that good! Dec 16, 52 0 18, Visit site. Sansui Integrated Amplifiers AU Reviewed Jul 09th, by Sansui My records sound better, my speakers have additional punch and definition with better clarity. With the mods completed it is a pretty damn good amplifier, now if I can just get mine back of my daughter!! The Au is like a classic Krell. All those buttons!!! Search Advanced…. Similar threads S. See how the AU performs, then next up may be a vintage turntable. I think the AU is a really fine amp after recapping, replacing the old flying saucer transistors that tend to go noisy, and adding the mods that Kevzep has developed.
