Product details:

Made of all aluminum brushed and oxidized material, with a good hand feel.
Symmetric design on both sides, emphasizing electrical characteristics from overall layout to component placement.
Two channels each use a 500W transformer for independent power supply, with abundant energy and no interference with each other.
8 10000UF 63V ELNA filtering capacitors.
Equipped with soft start protection, effectively protecting your device, improving the stability of the amplifier and extending its service life.
Each channel uses four pairs of Japanese classic Toshiba 2SC5200 2SA1943 paired transistors.
Equipped with dual meter display, beautiful and flexible.
