please read the JLH 10 watt Class A thread and try to understand why your circuit has some nasty features.. in that thread you can also find some real THD measurements on a good MOSFET implementation of the JLH.. at both 300mA and 1300mA ... It's not that I don't appriciate what you are trying to do here, but a MOSFET JLH is not as straight forward and actually has some caveats which you seem not aware of.. you should be a little bit more causious m8..

hi Mr.tschrama:
at first I want to tell you that my english is really poor,so many words I spelled is not correctly,sorry for this!
I planing to build this amp,as your advice:"some caveats which you seem not aware of",I just want to test if it can work as well as I think...one day I build this amp,I will tell you,OK?

By The Way:

this circuit wouldn't output 14W,neither 5w..
max output about 4W at 10ohm load..
AC40 volt throuth half-briage to DC36 Volt..
so output point is 18V,I=U/R=18/10=1.8A,
one chanel waste 64.8 Watte,so Irf530 need a
very large heatsink(32.4W),Use Irf540 or Irfp140
is much fit in this circuit...
P(output)=64.8x0.0625(rate)=4.05W
haha..
oh!Mr.tschrama:
I think You mistake from me..
the Quote is point to this circuit(not point to yours):
