Another D*A*M layout that I traced from photos is the Zoot Unit ZU-65, which is a Zonk Machine....   

I did see a couple of photos with what appeared to be a slightly larger input cap, but I’m not entirely sure about this.  

There are also variations on bias resistors, depending on Q2, with some having an additional 33k resistor across the 50k pot (same as this layout)

All the usual Zonk tuning and transistor selection requirements apply.
