Hello,
for 6 months I have been simulating with LTspice and tubes. In my project I am changing an OTL circuit form Alan Kimmel. Therefore I build some spice tube models with that tool: http://www.boschma.com/motega.html.
It's a pretty cool tool, because you can build a spice model with some points out of the tube data sheet, but I couldn't make a model of the E810F. (perhaps I'm too stupid )
I've read in this Forum that your are using E810F models. That is why i'am asking if i can get it? I've modelled a E130l if someone need it?
Many thangs!
Best regards
Wolfgang

Hy,
yes you can create models of pentodes too. You need a matlab installation to run the script. Matlab is some kind of scientific tool and is very expensive.
But if I'm right (look on this webside: http://www.boschma.com/Matlab.html)
you can run this program without a matlab installation.
I don't know if this "work around" works on macs...sorry...
Best regards!

6J9P / EF180 model
The 6J9P.E180F is a hodgepodge of bits and peices I stitched together but seems to be fairly accurate with the exception of screen current:
