This is a power supply PCB dedicated for heavy duty class A power amplifier application. The PSU configuration uses CRC topology, which is particularly good for single-ended power MOSFET amplifiers and other similar class A amplifiers. The board also features dual mono structure so each channel of a stereo amplifier can be served individually by each power supply. For more exotic application even choke can be used in place of the resistors. Reservoir capacitor lead pitch : 10mm ( or 4-pin type capacitors) Reservoir capacitor maximum diameter : 33mm PCB thickness : 2mm Board Dimension : 150mm x 145mm Copper thickness : 2 ounce copper ( 70um !) for high current.
