This is the bare PCB of a heavy duty DC power supply, designing for diy of class A power amplifiers in particular First Watt power amplifiers that requires dual rail. The design uses CRC filtering configuration for good DC regulation. The PCB can house eight 10mm pitch leaded or snap-in type electrolytic capacitors( with maximum diameter of 35mm). The board can also be adapted for CLC filtering by replacing the serial resistor with dc choke.
PCB dimension : 144mm x 126mm. PCB thickness : 2mm. Copper thickness : 70um ( 4 times normal thickness !), Gold plated surface.
