Having a BSEE, a copy of "The Art Of Electronics" and many copies of the Amateur Radio Handbook I must say that this is the best book on electronics I have seen in years. All of the practical knowledge I had to pick up over a 30 year career with just the right amount of math for the neophyte. I had to learn about heat sinks from a Thermalloy catalog. Now, here it is along with many other fabulous explanations in one bound volume! Thank you to the authors for putting this together AND offering it at an affordable price!
