In what context did this model ever work in LTspice used as supplied? I can't
find one. I have no trouble with any other amp model I need to use, but in
all the realworld CA3140 situations I have emulated in LTspice, THIS model
fails, with an interesting variety of errors.
Now I am NOT interested in what spurious ways I might be gettign it WRONG,
I'll work that out in my own time withotu bothering anyone at all. Right now
I want to know if it EVER worled RIGHT. In complete context please. If I can
see proof that it works, I'll start to figure out why I can never use it.
(It's interesting to me that on the web at larghe, though this model has been
accepted gratefully many times, no-one has ever actually said whether they
managed to USE it or not.)
