INTRODUCTION 

The  design  of  this  MOSFET  power  amplifier  is  referenced  to  the  circuit  design  of 
Harman-Kardon Citation 12 amplifier. The values are modified according the suggested 
values  by  Nelson  Pass.  Each  channel  is  capable  to  delivery  75W@8ohm  and 
150W@4ohm  power  to  the  speaker.  The  power  can  be  supplied  either  by  AC  or  DC. 
Testing points are added. The output current can be set by a resistor trimmer.
