Some vacuum tube Spice 3f4 models I made up.
And some vacuum tube spice 3f4 models from elsewhere on the 'net.
And some done by Andrei Frolov
And some done using Andrei Frolov's software
And a zip file of some from Ayumi's Lab
And another zip file again from Ayumi's Lab
If you can read Japanese: Ayumi's Lab web page, I can't read it, but it looks interesting
RADIO LINKS to other web sites, lots of 'em!
