Hi all,

Here are some pictures of my personal Dunwich Wizard Fuzz #85. As it's quite a rare and now unobtainium unit, I decided to trace it.

I carefully took it apart, unsoldered all components, measured the resistors with a multimeter, measured the transistors with Atlas DC55 and noted everything down.
Then I traced it using Illustrator and drew a schematic on Kicad. I made sure my schematic doesn't contain any error, as I redid the original pcb layout on Kicad.

P.S.: there was a small mistake in my tracing. Gain lug 1 should go to ground. I made the correction and updated the files

I will gladly share the kicad files if someone is interested. I still need to create a project specific library for the symbols and footprints I used, so that it can be shared.

Here are my Kicad (version 5.1.9-0-10_14) files. I created a zip file in which are all documents you need in Kicad.
Just extract the zip file and put the extracted folder directly in your Kicad projects folder.

files corrected. Gain 1 now goes to ground, as it should

I had a mistake in my schematic/tracing: lug 1 of gain pot should go to ground.
I corrected both the images in my first post and the docs in the zip file.

Vince, thanks for such a great tracing job! This is is a really heavy doom fuzz.
I built it using this vero layout:

@vince69, would you be able to make a PCB for the dunwich da120? That would be awesome if you could!

I suppose that the bottom layer of the pcb is to ground.... Do you maybe know what's connected to the top layer ? Thanks
