I forgot to check, so they should be the same...That's a brand new 12B4A model. Do you think that's better than the previous one in the pctube zip file?
They are a little bit different. Not huge differences.

Different enough to make a difference?

The 6T4 and 12B4 models posted by jazbo8 should work in TI.I'm sorry, I can't find any spice models for the 6AF4 or 6T4. It looks like these are all equivalents, but I have not studied them in detail. If anyone has a model for the 6AF4 or 6T4, I'd be really happy to have it, thanks.
Below are my 6AF4A, 6T4 and 12B4A models in Spice 3f4 format for use in TI. To use in LTspice change all instances of "^" to "**", without the quotes.

Hi
I'm looking for a spicemodel (LT) of the 4P1L tube and the corresponding DHT and DHP symbols. are there anyone here with the LT ready made direct heated symbol and corresponding sub circuits.

Is it not a beam Triode .Isn't the 6HS5 a voltage regulator? Are you thinking of another tube?
6HS5 Triode SPICE Model
I guess it can be used for audio... Thomas Mayer has some characteristic posted on his blog (no idea where it came from), so I built a model based on that.

THanks, I’ll give it a try
It’s a high voltage dual triode, compactron base.
Looks very linear and may be suitable for a two stage amp, etc
