the spice models I need:

ECC88(6DJ8)
ECC81(12AT7)
6N3P(2C51)

I got all of these models, but I can`t use them in CM 2000.

in any of these programs you should take the Model and back into the curves in the RCA tube handbook (or other). The Koren models work well but they are in need of adjustment of some of the variables to acurately portray what's cookin down there in ECC83 land.
