But if you do go back to it, I'll be happy to participate. There are
probably enough of us who have the necessary hardware to do some real world
tests.

And back to Mike Dennison's query: I am still using the Hafler audio amp,
and running 250-300 watts at 137 kHz. I should probably do some 2-tone tests
to evaluate the linearity. I can testify to the low efficiency, however, as
the shack is comfortably warm.
