With 0.35, I had to make gmin=100u.
With the latest, it worked fine as is.
Al, I think it would really help if you made a release. All of the distros are
stuck at 0.35,
so that's goi

I was looking at a version of the manual from Sept 20, 2006, so maybe it's out
of date. But it gives two options for the tran command:
transient start stop stepsize {options ...}
transient stepsize stop start {options ...}

You're specifying a 10 ms step size (first parameter in the tran command), and
it looks like that's what you're getting. The period of a 60 Hz sine wave is
16.6 ms, so you're getting fewer than 2 samples per cycle. Try changing the
step size to 1 ms and things should start to look better.

In this case, the solver will not need to add extra steps internally.
You specified a sin generator, whose output is a simple function of
time, and a resistor. The whole circuit is memoryless. At 60Hz, the
period is just 16.6ms. With a 10ms step size, of course you're going
to see an aliased wav

Thanks for all the replies everyone, but I think I should have started
with something a little simpler and built off that. Now I can't even
model a simple AC source in series with a resistor...I tried to do it in
straight gnucap and eliminate gschem to try to narrow down the culprit.
