Someday, I'll have to learn Spice
Sounds like today would be good.

Load LTSpice and give it a try. You won't learn much if you have someone else do it. We're not here to do your work but, if you have problems, we're here to help.
Hi,
Did you go to the IRF site too look for a model first?
That's the first place to look, so you dont have to create one yourself.

I've also learned not the ask thing like how do you make a 'model' for an SCR in spice, so I am asking where do I go to learn how to. I have the .sub file. and I found out you can only have one include in a design. Again, where are the instructions, manual, how to's for Spice,
In other words, you don't have to give a fish to eat, or even teach me how to fish, just tell me where to go to learn, please and
Thanks
