LUXKIT A901-C

Commentary

Stereo preamplifier kit using battery drive system.

As an ideal power source, it has a built-in battery to ensure a large instantaneous power supply capability and a pure DC power supply.
The A901-C is equipped with an automatic charging circuit and a battery monitor with voltage detection.

We pursue simplification of both circuits and materials to achieve both high performance and high stability.

We use oxygen-free copper wires for power supply and non-magnetic materials for signal line amplifiers and other components.
In addition, oxygen-free copper wire lead capacitors, copper caps and lead resistors are also used at important points.

For each circuit of the amplifier section, various audio capacitors such as Styrofoam copper foil, Super Twist El, AR type electrolytic, and Blackgate are used.

Equipped with high-gain equalizer circuit.
