From: Tom B on 14 Sep 2009 09:58 You should read this page. http://www.beavisaudio.com/techpages/SchematicToReality/ and one thing I forgot to mention. Those two electrolytic capacitors are polarized. They will have a ( NEG - ) stripe down one side. that side has to be connected to the ( ground - ) side of the schematic. Even if the battery + goes through some other parts the + side of the cap goes towards the B+ and the negative side towards ground. In your case the + side of the 100uf cap connects to 100ohm resistor and then B+(9V). The 10uf cap has it's - side connected directly to ground. Both have their negative sides noted as shaded grey in the drawing. The IC will have a notch centered in one end. Pin 1 is just to left of notch. Pin 8 is to right of notch. There is nothing else you can plug in backwards on that circuit ( except the battery ).

There's a .047mf and a .0047mf but I can't find a .000047mf. Can you advise me on this? ---------- I've got everything else needed in the cart including a range for the CX 220pf, 330pf, 470pf, 560pf, 680pf Thanks, Steve

Tom, You sound like an guy that has fiddled with this stuff before. Just looking at the schematic, there isn't anything in there that clips.. other than the gain of the opamps causing them to run out of rail. Most pedal type distortion boxes use diodes to make distortion, this just makes the opamp clip.. interesting.
