please see attached. This is rev 1 and I hope to have included most of the comments I have received from the beta builders, plus my own experience. We have tried to think about the most common issues and provide explanations, let's see if you can find more...
In fact, the R3 should be a breeze to build. If you are careful with that soldering iron, and putting all those LEDs the right way, and don't mix up the PNPs and NPNs, you should be good to go pretty quickly.
The PCBs do NOT have the component designators printed, but the component values. For development and trouble shooting work that might make it more difficult, but for building (especially for the less experienced builders) that should make it more easy - painting by numbers, so to speak.... ;-)
Attached are also the schematics of the amplifier and regulator, with typical voltage levels. These are from my Paradise, while it was still warming up, so please don't get nervous when yours are not matching 100% to these - if you are in the "ballpark" thats good enough. (For the pro's, you will note that I also have a little offset around the input stage... ouch...)
Hope you like this stuff, I will try and update the builder's guide as we go along and repost....
