I posted in Spice model page, try it.

Looking at Koonw's graphs, he shows the triode strapped parameters, and the triode curve fit looks good. In your simulation you should be able to use the tetrode model and simply connect g2 to the plate.
Yes that is correct, but anyway I built the triode model as requested.

I just want to understand is it how it was supposed to be? In model anode current is practically doubled.
Thank you for pointing out. Here is the correct model:
