Accuphase E-370 Integrated Amplifier AC100V From Japan

The preamplifier section features "AAVA," a unique volume control technology that does not use variable resistors. The power amplifier section employs a "low-noise instrumentation amplifier configuration" with balanced signal transmission from the input terminal to the output stage. A current feedback amplification circuit is used to feed back the output signal as current, achieving low impedance in the feedback circuit. The output stage uses high-power audio transistors driven in parallel push-pull configuration per channel, ensuring an output of 100W x 2 (at 8Ω). The protection circuit and speaker terminals are directly connected to enable balanced remote sensing of the power amplifier's negative feedback, and the latest MOSFET switches are employed. The power supply section features a larger, high-power capacity, high-efficiency transformer than the E-360. Two 30,000μF high-capacity, high-quality aluminum electrolytic capacitors are equipped for filtering.
