You mean this->LIMIT(..... ,0.0,1.0e16). Hmmm, it's there.
Yes, it should be LOG for the PSpice program. I had forgotten that I modified it for Micro-Cap (LOG->LN) which uses it's own flavour of PSpice. Either will work in LTspice. You did notice that I said "flavour" and not the actual PSpice application?
Works OK here. It's the two zip files in posts 782 and 783 on page 79 of this thread. I'm using the forum defaults for thread display.
Sorry, I've never compared them to any other models.
Yes it is, but it does not work as is. IMHO it is much easier and cleaner to use MAX as I have shown.

5842 SPICE Model
Here is the model per your request, btw, try not to use the Duncan library, there are better models available from Ayumi, and Frolov's Curve Captor...

.ENDSHello jazbo8,
I'm happy that I have now found the way to run tube simulationes with Spice. That was a long way for me. In the past i was working old-school to calculate electronics by datasheets, templates and a little calculator
Thank you for the model, but this one i integrate this morning in the tube file on my computer and it dos not run. I think i'm to stupid for Spice

It may be something to do with your simulation... the model itself is ok. If you don't mind, please post your .asc file (rename it *.txt), so we can take a look at it.
An externally hosted image should be here but it was not working when we last tested it.
A NOS Raytheon 6sn and a chines shuigang 6sn7. Simular results wth alle other 6sn7 I has except TS reissue
I have a new solution. I use the Models from Steve Bench ( :: View topic - Drop Down Menus for selecting your tube ). With this solution i have the Tubes i need.
Are there anyway in the Internet models of lundahl transformers?

Given the large distortion generated by the Tung-Sol, it would suggest that it does not have the same characteristic as the others or even its own datasheet, poor quality control perhaps?
What are the primary impedance and secondary taps that you plan to use for the above OPTs?
The LL1620 should run with 6k/8Ohm and the LL1623 switchable in two configurationes with 1.6k (SE) and 5.6k (PP) to 8Ohm.

I tried making the following models based on the datasheets, hopefully they are close enough...
