Well, I went to TapeOp, built the kit, and have the schematic. However, it wouldn't really be my place to give it out (as Scott created it specifically for TapeOpCon). But, I can tell you that it probably is not worth your while to make this circuit.
First of all, Scott designed this circuit to be as simple and cheap as possible so that a group of probably more than 100 (many first-timers) could build it in an hour or two for less than $20. This, as Scott has admitted himself, necessitated many compromises in design. In other words, the project was meant to teach the group about compressors- not create one that was "top notch." While I haven't listened to mine yet, Scott said that "it sounds pretty good for what it is." My recommendation would be that, if you want to go through the effort of reverse engineering a design (or even building one), there are probably hundreds of better choices. It's kind've like "Why build a bicycle from scratch when you have the complete instructions and parts for a Porsche?"
Anyway, do as you like. Just my two cents...
