I keep responding to your mail address, Al - sorry about that, I didn't
realize (yet again) the mailing list doesn't set the Reply-To field.

Oh okay, I didn't realize this. Thanks a lot for the pointer.
> If you need better, google for a spice model. (or in the future ..
Verilog-A model) .. Op-amp models are usually subcircuits, designed
for a particular variant of Spice. Some work, some don't. The only way
to know is to try it. These models have lots more detail. If you are
just beginning, you are better off without it.
In future development, when I have adjusted everything to my needs, I'll
indeed start to play around with certain OP-Amps as the stuff I'm doing
is exploiting them quite a bit regarding their GBP for example. Not all
Op-Amps will do.
For now, however, I'm just playing around - still I tried using real
models as this will be what I'll be using in future.
And indeed, I got it running - kind of. As an example, I took the model
for the most simple LM324 from
http://www.national.com/models/spice/LM/LM324.MOD - I had to rename the
subcircuit as gnucap appearently cannot cope with slashes in the
subckt-name (originally it was "LM324/NS", I renamed to "LM324" and it
worked).
Thanks again for your help!
Kind regards,
Johannes
