Looking at the THS3062 data***, I don't see any
plots for opamp supply current vs frequency for
full-scale output voltage swings. To me this is a
bad sign of a serious issue that's been overlooked.
Check it out, John, and let us know.

I was sort of looking at a different output a bit like your class A,
ftp://panteltje.com/pub/amp1.jpg

This is classic and has about 50 Ohm output.
Have only simulated DC... have to finds some transistors.
Wha tdo yo uthink of the output stage?
(Never mind the rest I just filled in what I felt like).

That's a good example of a circuit that will get into
serious trouble above 100kHz or so... No good way to
rapidly turn off the unused transistors.
