Default Tina TI Pspice Model 5670 aka WE396A Ayumi

Newbie here at TinaTI Pspice and adding / simulating tubes. I've noticed a difference in the Ayumi models for LTSpice and TinaTI, however, I can't find the 'secret decoder' ring. I tried reading from Ayumi's site with GoogleTranslate, but still no luck. I'm pretty sure that somehow the parameters for Ayumi are run through an equation and the PARAMx PARAMy values pulled from these and then reinserted. The tube I'm interested in is the 5960 which is close to the WE396A. Jazbo8 provided an LTSpice model, which I tried to insert by changing the file from .inc to .cir, however, that didn't work. Probably a bad idea, but that's part of the learning process. Right below the post I noticed cogsncogs provided a post for a different valve in both LTSpice and TINA TIpspice, which when I tried the TINA version, it worked fine. When trying the LTSPice I get error message about operand ** line 15 or 16. Any help you can provide is appreciated. Thank you in advance.

Default New generic Spicemodell copes secondary emission!

Hi all

One year after my introduction of new precise vacuum diode and triode spice models, I'm proud to present my new generic pentode model which is capable to mimic the secondary emission effect.
It has its roots in Derk Reefmans approach to describe this effect, but is highly improved to get the related parameters independently.

As a first tube, i fitted the 6L6GC based on the GE datasheet.
You will find the spice code here:

all the best, Adrian

Adrian, what tool do you use to find pentode params to fit the graph using your model?
