Pink Jimi Photon Photonic Juergulator Mk 2
Here's Jimi's (second) take on the Harmonic Percolator circuit. Like the original, Jimi's circuit uses germanium and silicon transistors, but with much more attainable components. Here's a link to his schematic, and be sure to read his notes on changing transistors. The 47µ cap he references is located between the 2 transistors directly in the middle of the board. I've added polarity protection and power filtering. Pots can be mounted from the solder-side of the board using right angle PCB mount pots.

so i verified it! used pnp Ge mp42b, hfe=55, bc 550 hfe 400, tweek pot used 50k, & changed resistor from 47k to 1k ( in my case), Perc pot = 1mom & remove 470k resistor, volume=50k, harmonic 100 k, or 200k, or 500k. I left 200k. Its a great harmonical saturated fuzz from hard to velvet soft sounds!
ReplyDeleteMan you're knocking them out! Thanks Zzoyd!
DeleteO, thanks you, David!This Man inspirated me on all that fuzzes =) https://www.youtube.com/watch?v=IzrTL0RnSVY&fbclid=IwAR1kcV6fcedRa7imF_g9MC2e1gkuClwV4rcUEpclXhVjJZ4LMiJkRrXW1JA
