EL82 or 6P18P model?
I'm hoping for a triode model for 6P18P. I'd settle for EL82, as that is supposed to be the equivalent. I haven't been able to find either one. Maybe someone has a good model they'd like to share? If not, I wonder if I can go to the well again...

Thanks!

Thanks, Wayne. Yes, I was looking for a model for LTspice.
I was also looking for models for the 7199, including both the triode and pentode sections. Somewhere along the way I came across a 7199T (triode) model you created using Curve Captor; here is that model:
Would you also happen to have a model for the 7199 pentode section? I have an old Koren model that doesn't give realistic results when used in the original Dynaco ST-70 circuit.
Thanks again if you can help.

Here's one I made a few years ago. I haven't tinkered with it in quite some time, so YMMV.Would you also happen to have a model for the 7199 pentode section? I have an old Koren model that doesn't give realistic results when used in the original Dynaco ST-70 circuit.
Thanks again if you can help.

What do you mean by "spice format"?

Hi all,
Does any of you have a spice model for the double tetrode QQE02/5 or 6939 ?
It's this tube: http://frank.pocnet.net/sheets/128/6/6939.pdf
Thank you!

Does anyone know if there are LTspice models for DHT types 30 and 31? These are triodes meant for use with battery powered filament supplies, probably for portable radios. Might be fun to play with for audio, right?

Does any of you have a spice model for the double tetrode QQE02/5 or 6939 ?
This is an unusual tube, neither ModelPaint nor Ayumi's model builder would work properly. So your best bet is to ask someone with an uTracer to trace the characteristic of the tube and build a model for you.
