Tooling up!
I just ran across a very useful-looking electronic tutorial site. This pointer is to the second lesson, Your Laboratory:

And the pointer to the index itself:
http://mysite.du.edu/~etuttle/electron/elecindx.htm
And, please don't be intimidated by the size of that index. Most of that stuff will NEVER be used by any of us, and a good deal more will be of little more than academic use to only a few.
It must be admitted that this really is not a site for beginners. The author doesn't hesitate to use equations to describe what the circuits are supposed to do, and that can frighten a lot of people, especially those who developed algebraphobia in high school. But, those equations are there to help you. With a little assistance from those comfortable with algebra, you WILL be able to figure out what the equations are telling you, and how you can do useful things by bringing your pocket calculator into the fray. A simple 4-banger calculator will do most of the work, and if it includes square root, you've got the tools to do the vast majority of calculations you'll need -- if you need to do any. A scientific calculator (trig functions, exponentials & logs, etc.) isn't needed. They are nice for occasional special problem, however.
On the other hand, don't hesitate to burrow into any of those articles and ask questions about what confuses you. If no one knows how to answer you, then maybe someone will do a little burrowing of their own and come up with an enlightening answer to share -- or maybe we'll just all stay confused. ;o)
(Aaron, note chapter 10.)
Disclaimer: I've only examined a few of the entries, and "Your Laboratory" seemed directly relevant to what a lot of us are doing, which is why I submitted the pointer directly to that page. The other stuff I've examined looks pretty good, so I'm thinking if the math isn't too bad, many will find them useful.
