Sansui AU-11000 - Integrated Stereo Amplifier (1975-77) In Really Nice Condition!

Wow In Really Nice Condition!

We don't see very many of these in this condition. Original box, packing, and manual are not included. White background is a stock pix.

Made in Japan.

NOTE: THOUGH THE WHITE STICKER ON THE BACK SAYS 220V - THIS UNIT IS RUNNING IN 120V  (FYI, IT HAS A MULTI-VOLTAGE TRANSFORMER INSIDE AND HAS BEEN SET TO USA VOLTAGE LONG BEFORE WE TOOK THIS INTO THE STORE. PLEASE NOTE LAST IMAGE THAT SHOWS ALL VOLTAGES)

(from Wikipedia) The amplifier is known across the audiophile community for its high-output power and low Total harmonic distortion (THD).

The AU-11000 has an output power of 110 watts-per-channel, and was one of the earliest home audio amplifiers to use multiple transistors per channel using a "Push-Pull" method to add more amplification power. The AU-11000 uses independent circuitry in the amplification process, in such a way that, each individual channel has its own circuits. This means everything from the power supply to the bias control board all have 2 identical and independent circuits per channel to separate the 2 stereo channels. This also minimizes the Total Harmonic Distortion (THD) within the amplifier down to 0.08%.

The AU-11000 has its own power protection built into the amplifier. When the power switch is turned to the "ON" position, the power light comes on as green for a second, and turns red for a few seconds until the power protection circuitry has confirmed it is safe to power-up. Once it has finished, the power light turns and remains green until the
amplifier is turned off. The AU-11000 also has its own block diagram printed on the upper-front casing. Sansui designed the AU-11000 with the input, output and speaker terminals on the sides of the unit. The rear of the unit has the power cord and outlets only.

The AU-11000 has features such as a logarithmic volume control, a 3-position level-set muting, a -20db mute switch, 3-position high & low filters, 3-Band Linear Bass/Midrange/Treble controls, 3 optional frequency settings for Bass & Treble controls, 3-position Tone
Selection, A & B Speakers, Tape Input/Output control, 5-position mono-stereo selector switch, Tuner input, 2 Auxiliary inputs, 2 phono inputs, 2 rear 'always on' power outlets and 1 switched power outlet that is controlled by the units main power switch. There is an XLR input for Tape 2, and a spring-loaded ground connection plug.
