This listing is two pieces of bare PCBs of a high power amplifier, output power 150W( +/-55V)at 8 ohms loading. The design is based on Symasym5_3.
The boards are fabricated with 2.0mm thick fibre glass(FR4) , super thick copper and double sided solder resist coating for best reliability and durability.
PCB dimension : 138mm x 70mm ( each channel).
PCB thickness : 2.0mm.
Copper thickness : 75um -- FOUR times normal process of copper thickness.
Tin plated surface.
We provide schematic and part list to buyers by EMAIL( to be attached with the shipment notice).
