Here is a highly desirable, very well built old school Sansui AU-555A integrated amp. What can you say - 38 years old - working fine 7/10 rating is very harsh and reflects age and the some chipping of the top backside of the stylish wood cabinet- otherwise it is more like 8/10 faceplate- - they just do not build them like this anymore.
Despite being compact, this amp is heavy. Email me at apt_one@yahoo.com, price is firm, compare what this sells for on ebay!
SANSUI AU-555A VINTAGE SOLID STATE AMP NICE!! ask for photos
All knobs and buttons work. Very good vintage sold state amplifier. Made in Japan. Tested in good working order. Vintage Sansui AU-555A Integrated Amp 1974 Vintage Sansui AU-555A Integrated Amp 1974. The follow up amp in the AU series that started it all.
Description Vintage Sansui AU-555A Black face Integrated Amp circa 1974. The first AU series set the standard for Hi Fidelity integrated amplifiers and these amps are still brilliant today. The 555A is slightly more powerful and probably a little warmer sounding than the original 555. This is a fantastic Amp that looks great sitting on a cabinet with a classic 70’s turntable by it’s side. Delivering great audio detail and a rich tight sound, this is a classic Vintage Amplifier that has made a lot of listeners very happy indeed.
Controls for Speakers A, B, A+B, Treble, Mid Range & Bass, Volume, Balance & input select. Switches High & Low filter (early Dolby), Loudness, Stereo/Mono, Tape source (input). Speakers A & B on/off. Inputs Phono 1 & 2, Aux, Tuner & Tape (switch). Aux can be used for CD, DVD, VCR, Headphone jack. Pre-in Main-out RCA plugs on rear. This amp can be used as a pre-amp or power amplifier. The Pre-Amp, inputs and power supply are all shielded.

The Integrated Amplifier of PB series which upgraded AU-555 and renewed the description and the design.
The whole page consists of silicon transistors.
The SEPP-ITL-OTL scheme of the pure complimentary darlington circuit which adopted the silicon transistor as the power transistor is adopted.
In order that an electrolytic capacitor may avoid the ill effect which it has on a music signal, as much as possible, using a hardwired-connection circuitry, a capacitor is lessened, and a required fraction makes a circuit impedance high and is using the Mylar capacitor.
Moreover, electrolysis connected the Mylar capacitor to the surely required fraction in parallel, and has improved the high region property.
The triple tone control of Bass, Midrange, and Treble is carried.
Moreover, since it is an it1 step type control, a special NetWare program and a more exact correction of a room acoustic can be performed.
Especially a preamplifier part uses the low-noise silicon transistor sorted out, and makes the noise small.
All the amplifying circuits from the first rank to the final output stage are constituted from NF amplifier, and the frequency characteristic, distortion, and S/N are improved.
A preamplifier part and a main-amplifier part are detachable.
The ripple-filter circuitry which became independent, respectively is attached to the main amplifier and the preamplifier power source.
A hum component is intercepted completely by this and the power source is stabilized.
Two speaker outputs are carried.
Functionalities which can be simultaneously monitored at the time of a low NF type filter, a high filter, a loudness control, and a sound recording, such as a tapes monitor circuitry and a headphone termination, are carried.
