Sansui 999

Search Everywhere Threads This forum This thread.

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.

Sansui Integrated Amplifiers AU Kevzep has created mod that ment to increase the bass which is worth a try, sansui 999. In good condition important to say this amplifier is a true musical bomb; What can I say more?

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.

But at least we agree on the SQ of the AU Moderators online. Service manual has no schematics. I guess I am saying the amp wasn't that cheap and also the 'you get what you pay for' rule often doesn't apply to hi-fi. 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.

Here are the original "flying soccer" transistor replacements used by Sansui, followed by modern subs of even better quality as suggested by Kev on AK:. It is clear and musical. The was a no go.

Reviewed Oct 31st, by wpettit. As soon as i put a few listening hours under my belt i will post my opinions. Just wondering if anyone here can offer some info on maintaining and looking after this amp. Reviewed Jan 17th, by Bmwi. One of the best integrateds Sansui ever made. It is y and this is not a joke Hi-Fi Jul 21, rturk3. Two tape decks can be used simultaneously and a TapetoTape reprint switch is mounted. Last edited: Jan 5, Top Bottom.

I have the opportunity to pick up one of these amps which was reportedly restored. I am playing mine with Italian-made speakers from the s and I am amazed at how well they match! It is clear and musical.
