A Juergen Haible Krautrock Phaser (Schulte compact phasing A clone) was born as standalone Device.

Additional Mods in some of my Krautrock Phaser:
CV MOD: (this PCB was tested and works) let me know if you want a pcb.
D3 isnt needed from my POV.
if you still have a -15/15V source (from Krautrock PCB) you dont need to install the extra C1,C2,C5,C6 (2.2uF-10uF for example)
