From the post
Here's another version of the Tycobrahe Parapedal, but unlike the previous layout, which is apparently a modified from the stock, we had some people in the forum trace an original one, Ciaran posting the schematic before I finished my trace, found here. The only thing different is I added the usual input and output pulldown resistors to prevent any popping.
Original Positive Ground Version
Theoretically, here's the layout but changed to more common Negative Ground
Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Tagboard Effects. No KiCad fragment has been drawn for this circuit yet.
