Pre-Altoids Box Version of a Microphone Pre-amp.

 

Before I built the microphone pre-amp housed inside of the Altoids tin, I built this one.  It has the input jack, output jack, and power switch located on three different sides of the box, so it isn't so convenient to use.  Also, it was difficult to figure out how to cram everything in there.  That said, this was a challenging and fun project.  I've had those 1/4" and mini-pin jacks since the 1970's so it was good to put them to use.
