Sansui's masterpiece in tube technology. Sansui’s Product Info for this model: Sansui Electric Co., Ltd. will revive and produce 200 units of the AU-111 tube integrated amplifier released in 1965. As a result of the efforts of the engineers, who were delighted with the fact that the production instructions for the output transformer, which is a key element, were maintained and the manual production equipment could be operated, it became possible to produce. The AU-111 enables attractive playback tones from analog records to new      1. Ultra broadband output transformer, power transformer with excellent regulation. The output transformer is a super broadband, large capacity and large capacity output and has a playback frequency of 100 kHz. In addition, the power transformer is also an original power transformer with excellent regulation. By combining the combination of names, it is possible to take out the amount of energy without waste with little constant loss and get high performance with low distortion rate. Both the output transformer and the power transformer, which affect the life of the vacuum tube amplifier, have been revived with the original specifications.   2. The output tube uses 6L6GC. The circuit system and tube are the same as the original, and the output tube uses Class AB push-pull bias of 6L6GC, a high power amplifier with an effective output of 45W + 45W and a multiple negative configuration Feedback circuitry that is flat across the entire band.   3. LF amplifier configuration for all additional circuits. The AU-111 uses a luxury 4 stage circuit including the cathode follower in the control amplifier section, and the entire amplification circuit from the first stage to the last output stage is made up of LF amplifiers. It is characterized by low noise and low distortion.   4. Special consideration when playing analog records. For the analog playback of records, we have made a perfect changeover to the MM cartridge with the 2-stage 12AX7. Two types of support have been made for MC cartridges. A separate A-603S input transformer for the MT9P socket is prepared for high impedances (30-100Q). The low impedance is supported by an external transformer or head amplifier recommended by the manufacturer of the power cartridge.   5. Tone circle with variable rise and fall points. The frequency of the rise and fall points can be switched in four stages by controlling the tone: 250 Hz and 500 Hz for the lower range and 2.5 kHz and 5 kHz for the high range. In addition, low and high frequencies can be defeated independently.   6. Integrated separable, equipped with volume of the power amplifier. Equipped with two pre -out systems and a power amplifier in, which enables pre -main disconnection, allowing the AU-111 Vintage 1999 to be used as a preamplifier.   7. Wiring without using a circuit board. With internal cabling, the direct cabling via the wire ring is done manually as in the original, so that the sound quality does not change due to the material and pattern of the circuit board.   8. Uses original brand electrical parts. The same brand is used for the filling capacitor of the power supply unit as at that time. In addition, we searched for and introduced an oil capacitor (Non PCB), which has an excellent rating as a capacitor in terms of quality.   9. Stainless steel is used for the main housing. In the future, it can withstand long-term use. In addition to sound quality and strength, the sheen of stainless steel has the advantage that it cannot be offset by coating or painting iron plates.   10. All 6 gold-plated input connections. It is equipped with 6 inputs that correspond to the increase in the number of connected hardware devices and supports the spread of SACD and DVD audio.   11. Gold-plated speaker terminal. The load impedance of the AU-111 is 8? and 16? with dedicated terminals, which is in line with the traditional 16? design specifications of the famous instruments of the past. ? Check my feedback as a seller and buy with confidence! Note: if you want shipping to AK or HI, there will be a shipping surcharge - message me for info. Note: this was released as a special edition of 200 units on Nov 1st, 1999 in Japan only (which sold out immediately). It is a 100v model, you’ll want to use a step-down adapter for it, which I will include.
