2011/3/5 Dominique Michel :

Indeed in the video linked in the other thread I was explaining that a
huge part of the sound is due to the output transformer and to the
loudspeaker.

The prototype plugin I developed for that and linked here has a
parameter called "Output transformer quality" that controls the amount
and frequency of resonance due to the output transformer, which is
modeled as being linear for computability/performance reasons, but
still it shows how much the whole output is influenced by that thing.

The main strength of that plugin, indeed, is showing how feedbacks
from each part of the electro/mechanical/acoustic system have
influence on all other parts. In this sense, I don't think there's
anything more accurate.

In my very little free time I'm working on improving individual
components (especially the triode) and adding missing parts (eq,
loudspeaker enclosure, etc.)

True. I'm now investigating an hybrid physics-based/interpolative
approach for modeling the tube that was described in a journal article
by three Italian professors, in order to accurately model high
saturation.

Its parameters are extracted from those curves.
