    However, if the first watt is crap, why would you want another 1,999
    Just kidding, looks interesting, was it a prototype of something you put into production or ?

    I think the first watt was a great amp.

    No it was design to shake a table with 3 others , with Airborne Radio Kit.
    Then I used it in a outdoor PA.

    A monster the TX was about 2.5ft across on each channel. With 400,000uF on each power rail.

    But now with better MOSFET's it could be bigger, I also tried it with IGBT,s a wicked low bandwidth amp.

    I did wonder if it was designed for something other than Audio, I think you mentioned it before.
    Either way, a monster as you say.

    Likewise!! I was wondering about whether or not to point out that this wouldn't work as an audio amp for normal speakers... 2KW into 8 Ohms with mosfets rated at only 100V max drain to source.... No way!!
