Credit goes to Jeff for helping me compile the list of components; including his recommendations for the circuit layout
After I did all the basic engineering of the chassis/fitting all the relevant parts onto it, the amplifiers were then sent to my friend Brent Rowe at
www.fidelityaudio.com who ensured that everything was correctly wired together, and working properly. He performed all the relevant electrical tests etc, to ensure that the finished amplifiers were fully functional.
(((THE END RESULT IS THAT THE AMPLIFIERS RUN SUPER COOL - VIRTUALLY NO HEAT)))
Here is the component list:-
