I learned it in one night. For me, it's a lazy way of experimenting without doing the math by hand or picking up a book. And will answer a lot of these questions. I simply experiment with values until I get the results Im looking for.
If interested, I'll send you a link to my google drive which already has all the files you need along with tons of schematics. Simply copy the entire directory to HD and your done

You should have access and be able to right click and download. Once you download, copy the directory to your drive and execute scad3.exe from the LTspiceIV subfolder. Move the Schematics to the LTSpice folder so it reads the library files correctlyCheck out spreadsheets in tools folder, I use this for OPT numbers in some asc files
Start playing around with existing schematics. If you have "Teamviewer" or gotomeeting, I can log you in one night and show how to simulate and display the results, it would probably save you some reading. I'm not an expert and know enough to get you voltage, current, power and distortion figures. It's easy to "google" how to do this as well.
Warning: There's a few unfinished circuits I experimented with so proceed with caution. Once you sim for distortion, gain and some other parameters it will become apparent. Some circuits are copies of published circuits or circuits from this forum.
I can create a collaboration folder(read/write) on my sharepoint for those of you that want to collaborate and share some files/idea's
Enjoy

Spice is great for testing designs and to some extent bypassing the complex mathematics although that's not it's intention.
You still have to know how the circuits works in order to design it in the first place. And you are still required to do the basic math to get "into the ballpark" of the desired circuit operation.
Correct, but you can study other schematics and use similar circuits to inject in your circuit to get these ballparks. Once you do that, its a matter of tweaking the values until you find the results. After you do a couple schematics and get the hang of it, you'll learn to get the values closer each time. For me, I did very little tweaking once I bread boarded. Think of it as a stepping stone and visualization to actually understanding how the circuit works(learning theory). Some simply learn quicker than reading a book. I have learned a lot with this program and the help of this forum. If I ever retire, I'll start reading more....Thanks for all your help!
I've learned much more doing it your way than by reading, although I do also read. But messing with values in a real circuit to see how parameters are thus affected is something you don't forget about.
Would really llike to have that!email is vince@vrhea.com
Thanks!!

deafbyukhorns,
I'd love a link for what you have offered vinnie... learning ltspice has been on my list for some time!
.
I would like to have access to those sims.
Thanks.
