Hey, this is great! Instead of a table lookup, have you though about using a high order polynomial aproximation? That was what I was planning for the 12AX7. It doesn't look like that complicated a shape, 5th or 6th order should do it and it will be faster and less cachey than a high order interpolated table lookup. I'd be interested to see a plot of Vin in [-1,1], it looks like at Vin = -0.5 it's starting to curl back on itself, which is interesting. - Steve
