You are missing what I am aiming at. I read the original AH thread and I read
much of what you said too. I never set out to prove Kevin right or wrong. That
is the wrong way to start out and if I did I would have kept in that thread to
start with. Rather, I stepped back and said "OK, so what about this... I've got
all these nice toys so let's go in there and see whatever instabilities we can
find". Pure and simple curiosity about facts.

I'm trying to make some good quality measurements and that's where my concern
is at the moment. A quick evaluation of my quick-and-dirty clearly showed where
the error-sources where at the moment. Analysis comes in at a later stage.

Now, if anyone got a good idea for a good through-zero slew-rate amplifier?
