It may be interesting for you that I did some quite accurate triode LTspice models, especially regarding grid current.

More or less similar (in terms of mu) to what you request are the following of my models:
Sylvania 6948
RFT ECC81
electro-harmonics 12AT7EHG

You will find a zip of my models here:

The code of the last two models is also visible here:
