You are welcome, what are you trying to sim? Ayumi did a whole article on the Olson 6F6 amplifier, so the model should work pretty well.

Greetings. I'm just getting up to speed on LTSpice. Loaded tubes per post #117 and they work fine. Unzipped the Ayumi files from the fist page of this thread. Do those go in the \lib\sym directory? Do I need to manually create corresponding .asy files for each of the Ayumi tubes and put them in the sym directory?
