I'm modeling tube amps and just spent a half hour looking for some Spice models I had for various tubes. I seem to have lost them somewhere, so that's not happening again - Here's a link to Svetlana showing several Spice models for tubes. A couple of other great sites are Duncan's site (referenced by the Svetlana page) and the "PAEng" site.'Spose I could have just copied the models to my local disk, but maybe some of you will find them to be interesting. Besides, I probably would have just lost them again.
