Lawrence,
I can push it to 1000 watts but the voltage is over 60 and the FETs don't like it. I am using the 79 material. It doesn't even get warm. I'll keep it at 900. I have another one with two FETs that does over 500 watts with 55 volts - so I am not sure what is happening. I was just wondering. Thanks for the data. Hope to work you sometime. I have been real busy and not too active in the last month.
