Strange: m_pi should be declared as a constant in
/usr/share/permafrost/lib/m.pmf or similar location... Oops, perhaps I
missed a "import m;" at the beginning of amp.pmf. Could you try that?
BTW, I should have put the sources online for those who wanted to try
it... my bad.

It does a full simulation. What is not modeled is the grid current,
hence no blocking distortion.

In the sense that it sounds bad?

Yes, I know all of that. The problem is that each tube adds a
significant and difficult to handle nonlinearity, and it gets pretty
difficult to handle. With the current Permafrost you can model any
topology, but loops and conditions have to be implemented in C...
hence theoretically, yes you can, in practice it's really too hard and
the performance would be very poor.
I'm maybe going to work on this kind of stuff in the near future, but
I don't know yet what I will be doing in a couple of months. :-)
