This listing is two pieces of bare PCBs of a pure class A MOSFET amplifier, output power 100W at 8 ohms loading. The design is based on ALEPH X.

This is another board incarnation of this well proven amplifier. For those who want a kit of boards with the MOSFETs spreading more apart, please check "SE MOSFET full balanced 100W class A amplifier PCB !" in our shop.

The design features single-ended MOSFET class A balanced input and output, loaded with constant current source for excellent linearity and dynamic performance. Using 8 pieces of power MOSFETs, 4 pieces as output and 4 pieces as current source, the amplifier can offer 100W of uncompromised class A power.

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 : 275mm x 58mm ( each channel).

PCB thickness : 1.6mm.

Copper thickness : 75um -- FOUR times normal process of copper thickness.

Tin plated surface.
