The PCB has a board thickness of 2mm, and copper thickness of 70um !! This is four times normal board copper thickness, and two times copper thickness compare to our previous version.

We have also put is special focus on the thermal stability as can be seen on the new placement of the components.

PCB dimension : 105mm x 62mm

This is a single channel amplifier PCB. Two PCBs are needed to form a stereo amplifier.

We provide schematic and part list to buyers by EMAIL( to be attached to the shipment notice).

We also have the power filtering board with reference to First Watt amplifier series that is a perfect match with this amplifier board. Please check our other auctions.
