Happy Fuzz Friday everyone! This one recently got traced on the Aion blog (so go check out the full write up over there for more info and schematics). The Karma Suture is based on the Harmonic Percolator and has come in both germanium and silicon versions. The difference between the two are just a couple value changes, so you can build either version on the same board. Value differences are outlined below.
