Hi Ken,

I presume the amplifying chain itself should have a 0 degree shift with this 
method, or should it be 180 degrees (ie inverting)? And how much gain do you 
think is required - I assume that a single bipolar push-pull stage followed 
by a buffer amp, such as two common-collector bipolars again in P-P  (to give 
plenty of current for gate drive) and then the power FETs should be enough? 
For matching of the ouput stage, would common-source or common-drain be the 
right way to go?

Thanks

Alex
