I'll try and let this list know ;)

Wow, your ltSpice simulation sounds really real! I hoped to get ngSpice
to do the same.
That would be nice but unpractical? I heard ngspice is severely
afflicted by memory leaks when doing large/long simulations, I might
be wrong though. I try to avoid depending on it since I heard it's
been discontinued, and that of course makes my life much harder since
most (all?) of the ECADS device models on the net are available only
in some pseudo-spice format.
Now days I am
messing around with GNUCap and QUCS (http://qucs.sf.net)
to which I just ported my first tube model whose plate voltage/grid
current curves look like that:
great! looking forward to listening to those ;) the sndfile&resample wrappers that I patched into
ngSpice just work with
GNUCap and QUCS too. GNUCap is still quite unusable (segfaults on large
data sets) but I've elaborated on the QUCS hack - It's much slower
than ngSpice, but indeed more accurate (at least the timing); I'm still
to run some tests.. http://mir.dnsalias.com/oss/spicesound/qucs -
(highly experimental) - I did not get to clean it up last week as I
intended to and can't spare any time this week either.. - but I plan to
revisit the issue properly over the summer.
That's very cool Robin!
I'll give it a try later.
keep in touch,
Sure.
Cheers,
