From the post
There's a partial schematic up at FSB, missing all non-polarized cap values. I thought it would be a nice idea to take a guess at them. The values i selected should take the sound close to the original unit. Of course, if any of you have better guesses on the values, let me know. This design has three clipping stages (not gain stages as PGS demo suggests) and overall footprint isn't your usual copy of a copy. There's a lot of gain coming out of a single TL072 too...
