(LT)spice model for 6J7
Is there somebody who can supply me with a (LT)spice model of the pentode 6J7,
or where can I find a description on the internet? Browsing on the net myself did not give me any clue (for instance Duncan's pages or others).
Or, is it possible to modify an existing pentode model to get a workable model?
Thanks in advance,

To use this model in LTSpice change all instances of ^ to **.

Thank you very much cogsncogs!
At first I was afraid that nobody could help me in this matter
due to a lack of response.
