From the post
I came across this on FSB forum last night and it peaked my interest and seems to be a unique part of the fuzz history. As the emperor of the Germanium Deathstar, and as a loyal follower of fuzz I couldn't not make a layout for this. And come on, who doesn't love dirty, nasty vintage fuzzes, especially of the Germanium kind.
Note: this is PNP, do NOT daisy chain.
And one with onboard inverter so you can daisy chain it without any worry.
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.
