Has anyone migrated any of the vacuum tube models floating
around on the 'net to LTspice?

Hello Bill,
I did it once for a pentode. The model is included in the schematic,
but this can be changed using a library file valve.lib.
Then add instead .include valve.lib in the schematic.
It is very important to look on the used pin order. Everybody
has another pin order used in his library. It have to be changed
according to the pin order of your symbol or you make your own symbol
with the appropriate pin order. I couldn't attach it, because the
lines will be split by this awful YAHOO reader. I put it into this
group's Files->examples->apps folder. It is the file "pentode.asc".

Best Regards
Helmut

Thanks! I'm checking it out now.

Hello Bill,
I forgot to mention that the symbols for the triode, tetrode and
pentode are all in the "misc" directory of LTSpice. I am not shure
you were aware of that.

And again some more information.

The model in my example file is from this link:
