Pre-main amplifier of DIATONE by SANSUI OEM.

The NFB circuit, which tends to cause TIM distortion, has been fundamentally revised, and a new circuit design in which a feed-forward circuit and an NFB circuit are combined to make it possible to theoretically reduce any distortion generated in the power stage to 0.

On the material side, magnetic strain is eliminated by adopting copper plated chassis and using a large amount of non-magnetic elements.
In addition, a heat pipe is used to form a construction that avoids magnetic flux.

The power supply section uses a large power transformer that is independent of L/R and stage, and a high-speed, ultra-low magnification capacitor.

Newly developed equalizer circuit is adopted.

Equipped with MC head amplifier capable of switching between 2 positions and gain.

Running from 100V at the moment but I can supply the power converter.
