There is a thread in the stickies section for spice model questions. But here is one for the 6080 which is the same as 6AS7:

I save your above file and open in LTSpice. It is same as the triode.asy but the pin or netlist order for grid is 4 instead of 2. So you either correct it by editing the pin order to 2 or just use triode.asy. You can see the error in the last line:

PINATTR PinName Grid
PINATTR SpiceOrder 4
