you would find the above a beneficial approach and you would be pleased to
have expanded your methods in the way I have outlined.

I couldn't agree more - I spend hours poring over Morgan Jones and other books
of theory, and making excel spreadsheets of results and equations. As I said in
another post - I have acquired a scope and a wavegen, just haven't had time to
set them up and learn how to use them. Maybe when I retire I'll have plenty of
time to build valve amps and a garage full of measuring equipment. That's a
little while away right now, though.
