 +<​BR>​Step 1.<​BR>​
 +Start off with the PCB<​BR>​

 +<BR>
 +I'm building this Audio end first, because I wanted to look at the noise levels.
 +<BR>
 +<​BR>​Step 2.<​BR>​Add the MCP6002 Op Amp ( The flickr site has tags for the location of components)<​BR>​

 +<​BR>​Step 3.<​BR>​Add the two 25V(or better) 10uF electrolytic capacitors, this has to be orientated correctly, reference the stripe on the case<​BR>​

 +<​BR>​Trim the leads close as you can, hold on to the leads that will be removed as they'​ll fly off, or use clippers with a built in catch
