LTSpice model 12AU7 Ayumi Nakabayashi
I have the impression that the equations of the triode lead to extreme high voltages using following model below- anyone some experience with these and other models of this tube library?

Try this 6J6 model, it is very similar to the 6n15p.Hello all,
Does any of you have a model for the soviet 6N15P double triode?
It's this: https://frank.pocnet.net/sheets/113/6/6N15P.pdf
http://tubedata.milbert.com/sheets/093/6/6J6.pdf
You didn't state what simulator you are using, so I've attached a .txt file that includes 6J6 models for various simulators. Here's the LTspice version in the code box below:

* Modified Koren model (8 parameters): mean fit error 0.146816 mA

Do you mean 6KG6? If so, Duncan Monroe has a model for it, but I don't think it works too well... As for the KT series, they pretty much are the same as the KT88, but with different plate dissipation limits, so you can use the KT88 model for simulation purpose.Does anyone have good LTspice models for 6GK6/PL509 7308 6GU7 KT99 KT100 KT150 ???? I have a few hundred tubes but no good models for these. 6KG6 is listed in Ayumi Nakabayashi's lib but it's empty.

Thank you very much!
I'm using Simetrix, therefore it's easy to adapt.

Here's another one for which there are no spice models: 12HL7
diyAudio member smoking-amp posted curve traces of a triode strapped 12HL7, here:
"...pic is in "pseudo" triode mode (screen to plate): 0.5 V/step on g1, 5 mA/div vertical, 20V/div horizontal."
From thread http://www.diyaudio.com/forums/tubes-valves/271134-schade-cfb-exactly-equivalent-3.html#post4256614
Is that enough info to be able to make a spice model?

12HL7
I did some measurements earlier in the year for Bondini who supplied me with a GE 12HL7.
I attach the "DerkE" model I extracted, with the parameters and standard variances (in %) as well as a sample model vs measured match for Vs = 200V

Does anyone have a 4P1L model for triode operation?
I found the one on Ale's website but I can't seem to get it to work. 4P1L triode SPICE model | Bartola Valves
Or can anyone tell me how to get that model to work in LTSpice that would be just dandy too.
Thanks in advance,

Yes, but i am having adult beverage with wifey, watching "Death in Paradise" on the PBS. Remind me in the morning!

Strap g2 to the anode and it's a triode, right? It should work.
I also have Ale's models, but I can never get those to work in LTspice.
Thanks. But I'm afraid I feel a bit, er... behind the curve. I lack the know-how to convert the data from that image to a working (text file) spice model in LTspice. I usually use the Ayumi models jazbo8 and others have posted to this thread.
Is there a guide somewhere for converting the data in the image you posted to a .subckt file for LTspice?
