Germocide FuzzVerified
Based on the Germocide Fuzz
From the post
One more from the Dragonfly archives. This one is a must for us who have tons of low leakage, low gain germaniums on our hands. The name is describing the circuit well, as it takes 4 germs to get one ripping fuzz running. Note that this is "positive ground" circuit. You can always use a suitable pump to chain with your other boxes.
The Germocide Fuzz was something I designed when a forum member asked about what he could build with some low leakage, but very low gain (less than 50hfe) PNP germanium transistors he had.
