The first fuzz box.. The Satisfaction horns sound, the star of so many fuzztonic records. I had to make myself the perfect clone! Yes i built a couple of these before, but i wanted to build it properly.. This is what i came up with:
I did find them! A small stash of them actually! And i didnt have to sell my body to get them. Not RCA’s, but NOS 2N270: leaky, gainy, nasty 2N270s!
Next, i set up this testing board with a nice ZIF socket!
First good set-listen:
Q1 hfe 79 lkge 0.12mA
Q2 hfe 168 lkge 0.53 mA
Q3 hfe 131 lkge 0.70 mA
I tried inverting Q3 and Q2 but the distortion was oscillating..
