From the post
I was cleaning up my layout folders and noticed that i had not posted this one up. It's a slightly modified Machine. First of all, the second driver stage has a gain control now, per the Madbean "Macheen" schematic. Also, i found that using Si diodes and a smaller value for the Limit pot made this design sleekier and way more usable. Already verified.
