Spice Models
Hi,
anyone know where I can get spice models for the IRF250 and IRF9250 or their 240 and 9240 variants? 
IRF9250
Yes I would for all 4 parts if there actually was an IRF9250. Sorry I can't help.

THanks Fred  much appreciated.

you can lead a horse to water.......
I wasn't trying be totally obnoxious when I told you that there was no IRF9250, I thought you would go to the IRF website and confirm, which is what I did when I didn't recognize the number. The Spice models are there and take about 5 minutes of poking around to find.
http://www.irf.com/productinfo/models/ Five minutes with the Google search engine and an entry of "mosfet Spice models" and you would find: http://www.aplac.hut.fi/aplac/models/main.html I don't mind helping people who spent at least 5 to 10 minutes of effort on their own before expecting someone else to do it for them. Isn't this forum still called Do It Yourself audio? 
I misread the email trail. Sorry, not only can I not find models on the IR website, but I also can't read properly. So let me try gain
Thank you andy_C! much appreciated. Fred, you sound like my boss.
