I've posted up an additional schematic for a Hybrid amp for 39Watts class A which has EL34 driving complementary N&P source followers helped along by common source P & N mosfets which I have not yet ried, but which looks good in theory.
Those wanting to simulate the schematic, or actually try it out by building it may like to post criticism here.
