Hello Peter, well, I was pointing at many mentioned designs, which had
4cx350's, etc., working class A (and I agree I'm stating those as "high
power", although maybe for the rest of this nice list they fall into a sort of
qrp cathegory, hi). It was mentioned also a japanese gear which outputs 75
watts, also class A. Mainly to these rigs was aimed my question.
