4049 Cracklebox ....and 386 amplifier with built in speaker


I wanted the 4049 cracklebox like a standalone instrument, but it seemed like it couldn't drive a speaker on it's own.. so I removed the cracklebox from it's original box, and built everything in one another. Built in a week in october 2011. The amplifier schematic is from Nicolas Collins book Handmade electronic music.
