I haven't been able to find a 6JC6 pentode model for LTspice. Is there one?
smoking_amp posted some 6JC6 triode curves he traced
(2 mA/div Vert., 50 V/div. Horiz., grid in -0.5 V steps):

6JC6 data sheet:
https://frank.pocnet.net/sheets/049/6/6JC6.pdf
Is that enough info? (I hope so...)
I have a 6JC6 triode model I could post, if anybody's interested. I don't remember where I found it...

Looking for directly heated triode 5A6 Ltspice model
Dear All,
I have searched the forum in vain for 5A6 ltspice model. Is it possible to generate one based on the following data?
Datasheet with pentode loadlines, interelectrodes capacitance:
http://rtellason.com/tubedata/5A6.pdf
http://tubedata.jp/sheets/020/5/5A6.pdf
A Gentleman from Japan has made a triode strapped 5a6 loadlines:
5A6三結実測値からLTSPICEモデルの作成 ( オーディオ )
Any pentode or triode model are welcome.
Many thanks in advance.
Attached pictures are from the Japanese gentleman's website.

It seems that nobody has one...
So, let me rephrase my question:
Can somebody create one using the curves from the data sheets ?
2E22 SPICE Model
With a bit of tweaking, I managed to create the pentode model for the 2E22:

Here is a link to 300b with heater model: http://duncanamps.com/spice/valves/dmtriodep.inc
Triode with heater symbol: http://duncanamps.com/spice/valves/triodeh.asy as found in LTSpice and vacuum tube models
Look in the directory for files mentioned above here: Index of /spice/valves

So, is there a tutorial somewhere that tells me how to generate Spice models? I hate to keep troubling the rest of you! At the moment I am awaiting delivery of a nearly 100 year old radio that I would like to restore to operation. It uses ancient tubes (triodes only) that are likely to be of little interest to anyone here. I take it that some of you use a digital curve tracer of one kind or another. In fact I see the uTracer mentioned not far above and from looking at their website I get some information. At the moment it is too expensive for my purposes. That perception could change if I do too much more tube work but for now I would need a cheaper hardware option, if there are any, or is it possible to generate the models from datasheet curves?
