WRT the Reefman's models, if you want to use his models, you need to include the generic triode, pentode, etc. codes along with the specific parameters of the tube model, otherwise they don't work.
WRT to noise modeling, none of the commonly available models deals with noise, if you want to have it, then you need to add the required codes to the models yourself. But it is probably easier if you just add the noise sources externally as Merlin has done in his simulations, since you can tweak them on the fly, without editing the tube SPICE models themselves.

Thanks.
Does the generic tube model come first in the text macro file and then followed by the specific parameters, or the other way around, or does it matter?
I can't do that in Tina because it won't allow more than one source. Oh well. Thanks anyway.
This article:
http://www.ti.com/lit/an/snoa247b/snoa247b.pdf
talks about adding a noise source to their opamp models. The noise voltage stage is a diode in series with a resistor biased in parallel by a 0.1V voltage source. I tried it but ran into trouble.

In TINA TI there may be another way, but the easiest I've found is to combine the two into one subcircuit.
For example:
Code:

That's odd, I have not used TINA for awhile, but I thought you can have many sources in the circuit - it's one of the basic features of SPICE.
I meant "inputs", not "sources". Sorry.
Merlin had suggested putting a current generator set to 2nA sine wave in parallel with each tube. Tina sees those as inputs and objects.
I'm searching for a reliable model of the 5902 penthode. I already found a model but looking ant the curves that comes out from the simulation they are wrong. This is what I have:

6N14P/ECC84
Some preliminary curves and tube models for the 6N14P and ECC84. The models and curves were generated in uTgui and represent the performance of a single section each of an unselected bogey device. I will post additional models when I have sense of what a representative device looks like parametrically.
Note that you need the generic Koren triode model in your library to use these. (Get from the uTgui site)

Something to note that these models were built from measurements on unselected samples and probably represent relatively large divergences in performance from the "typical" tube of this type. Use at your own risk.

Here is a second 6N14P and a PCC84. I changed the plot from nine grid voltage plots to 8, 0 to -7V in 1V intervals.
The PCC84 actually measured closest of any of the devices I have measured so far to the measured operating conditions of the 6N14P in my latest phono stage design. (I selected them out of a dozen I have on hand)

If you have the triode connected Ea-Ia curves for 5902 or EL71, I could build the pentode model for you.
