The hardest thing to find in the book as far as I could tell was that dang little Clairex optoisolator (CLM6000) that he uses in just about every project. However, I was able to locate two sources for this part: Electronics Plus in San Rafael, CA: 1-800-321-4524 Quinn Mike Electronics in Oakland, CA: 1-800-559-1539 Other parts he uses (or direct equivalents) are still available. I sure wish *somebody* would write a new version of this kind of book...10 years is a long time in electronics (well, maybe not *analog* electronics! ;-) Thanks for the parts recommendations. I have a few things to add here: Yup, the book is terrific if you want to hack on this sort of thing. I've made and/or started to make most all of these things at one time or another. Check out the tube-sound-fuzz for a easy yet good sounding project. A company called PAIA in Oklahoma has the clairex parts available, as well as PC boards and/or kits for virtually all of the projects as well as most of the ICs that you need. IMHO - if you use Newark Electronics, or Mouser Electronics, the clairex part is the only hard to find part. All other parts are still produced and quite findable. Remember, Radio Shack is not *really* an electronics store! and if you want to hack analog electronics, you are just going to have to find your own favorite distributor; local or otherwise. I happily have used Mouser for years - your milage may vary. Regarding writing a new book... Some of those projects are from a book that he wrote, with which I learned basic electronics, in about 1975-1976, so that predates the latest (10 year old) edition. So, yes they are old, and yes, 10 years is a long time in consumer electronics. But there is a more telling point to be made. Craig now does mostly synth/computer/MIDI stuff I believe. "Guitar effects" have moved to these guitar effects processors now. Same effects as always - just done digitally now. So I am not sure if that makes the analog effects obsolete exactly; it may have made them cheaper. These effects processors are not made out of a handfull of resistors capacitors potentiometers and IC/transistors put together on a little board in a nice little box with a drug/sex name like Dr. Q, or Big Muff Pi silkscreened on it (oh, how I miss the old days...). Let's face it, they are computers, i.e., digital signal processors which run fairly sophisticated algorithms in software. The whole idea of building your own effect is thus much different than it used to be. I mean, to be cool now, you would have to build a digital signal processing board, then you program some algorithms into it, and you write new algorithms for new effects. 10 years ago, the average guitar player with a soldering iron and some practical sense could build whatever he wanted in less than a weekend, have some fun, amaze his friends, etc. But I would say that most DSP techniques are somewhat out of the reach, and perhaps out of the interest, of that particular kind of person. Just my opinion - no offense to those of you who do hack this kind of stuff. But DSP processing is not the same animal as practical electronic construction sense. Same effects are there - but the modern way of doing them is a whole lot different than those ancient analog ways ;-). T
