PCB layout:
Schematic:
I drew all of these based on pictures I found online. Most (if not all) the schematics I could find for these online did not match up with the detailed pictures of the circuit boards I had found. The only original one I own myself is the purple peaker and when I compare that to the copy I made based on the drawings, they sound identical. These really are wonderful effects, some more subtle than others.
My hope is that this will make people build copies instead of ruining/rehousing the vintage units.
Please give me a little credit and Dan Armstrong a hell of a lot more credit if this helps you in any way.
Enjoy!
