"OK, so what's this thing gonna look like when I'm done?" I'm glad you asked. Edward West has kindly provided some digital pictures of the preamp and microphone he built using the kit. As you can see from these pictures, he has done a fine job indeed!

Notice that Edward has chosen to use a BNC connection for the microphone (i.e. mic cable and preamp case), and an RCA connection for the preamplifier output. A nice detail, I must say, which prevents inadvertently hooking up the equipment incorrectly.
Here is a collection of all the images associated with the preamp project, which are scattered throughout these pages. All are available here for easy downloading.
