This listing is a piece of bare PCBs of a pure class A MOSFET pre-amplifier based on ALEPH P which is a balanced input/output preamplifier ( can be used as unbalanced in/out preamplifier too).


This is another board incarnation of this well proven pre-amplifier. For those who want a board in stereo and with integrated 128 steps level control, , please check "SE MOSFET full balanced +128 step volume control PCB !" in our shop.


The design features a single stage MOSFET class A for amplification, loaded with constant current source for excellent linearity and dynamic performance.


This is a single channel of audio. For stereo , two boards are needed.


The board is fabricated with 2.0mm thick fibre glass(FR4) , super thick copper and double sided solder resist coating for best reliability and durability.

PCB dimension : 157mm x 114mm.


PCB thickness : 2.0mm.


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


Tin plated surface.
