Title: A Perky Pair

...of Harmonic Percolators.

I'm really blown away by this circuit. I'd put off building it for a long time because of it's "vagaries," but it's  really unique, has a squishy Ge feel, but a clarity with chords that I've never come across in a fuzz before.

Used Russian PNP Ge (about 70hfe) and a BC109 for the NPN. I have some 2N3565 (as per the original) but found them too noisy.

Scored some beautiful glass NOS 1N695 diodes, (again, as per the original) they have a really low forward voltage- under 200.
I can part with some- $1 usd a pair + $2 for postage worldwide, if any of you diode junkies want to try some shoot me a message.

Two more home runs! Brilliant stuff. I'm in the same boat in that it's one I've never built and always meant to get around to and this is the tipping point.


I'm in for a few pairs of diodes. Sending a PM.
