Technics SE-A1010 Ver.3.0

Commentary

A stereo power amplifier based on SE-A1010 and using the latest version of high sound quality parts.

A MOS class AA circuit using a MOS FET is mounted in the amplifier element of the class AA circuit.
Class AA circuits achieve high power and pure class A voltage control by using separate amplifiers for voltage amplification and current supply.
In the MOS Class AA circuit, a MOS FET, an amplifying element with extremely high input impedance and excellent linearity, is used in the final stage of controlling the output terminal of the pure A class voltage control amplifier. In addition, a bipolar transistor with low loss and high output operation is used in the final stage of the current supply amplifier. As a result, a strong speaker drive power with low distortion is obtained.

We have adopted TAKE II Ver. 3.0, the latest version of an electrolytic capacitor using a bamboo fiber mixed separator for the power smoothing capacitor of a power amplifier.
By optimizing the mixing ratio of bamboo fibers in the separator, using thick aluminum foil, and using a special etching method, the equivalent resistance of this condenser has been further reduced and unwanted incidental sounds have been suppressed.

Left and right independent input level volume is mounted on the back panel surface, and fine adjustment is possible when bi-amplifier drive or multi-amplifier drive is performed.

Equipped with a large power meter that can be read directly from 0.001W. This power meter is equipped with a light ON/OFF switch.

Uses a high-capacity OFC power cord with polarity display.

Uses gold-plated input terminal.

OCC wire material is used for internal wiring.

Speaker terminal compatible with banana plug is adopted.
