The models on Duncan's page will be linked by either a yellow or a blue icon. The blue ones are to models meant for a version of Spice (Berkeley) incompatible with LTSpice. Most of the yellow link models work fine. You may find something useful for your driver stages.

Hi Nick
I have all of the common and some not so common tube models for LTspice, if you send me a pm as I suggested a few days ago I'll email them to you along with instructions on how to install.

You'll not find a model of the 813, that you'll have to create using paintcc version for pentodes as I have explained before.

Alternately go to my website and click the mail link on my homepage and send me an email.

Hi Nick,
Got it! Now quickly remove that link while you still can so you don't get spammed!

Kevin I was wondering if it would work if I took one of the beam tetrode models off the duncan amps page and edit it to the values of a 813 would that work or not?

Hi Nick.
There may be some parameters you can modify in say the EL34 model that would put you close to the 813. Frankly I haven't done this with pentodes, but it did work with triodes. The key is knowing the right parameters to change, and unfortunately I don't.

I would try paintcc - what you want specifically is paint_kip available here: http://www.geocities.com/dmitrynizh/...rams_image.htm


You might also want to join this group on yahoo groups, it's moderated though and joining takes a few days. The group orientation is towards big tubes like the 845, 211, GM70, and 813 so you might find some additional ideas here. Here's the link: http://groups.yahoo.com/group/GM70/
