I am building a Germanium Fuzz Face out of some transistors my grandad had. Only problem is, the circuit is oscillating like crazy. I see where the original trans were AC128 with an Ft of 1MHz. I'm using 2N65 for both trans. They also have a Ft of about 1MHz. I've also tried a
2N247 for the second trans. The circuit oscillates when I adjust the 1K pots 200kHz and higher. Gains for the 2N65's are 85 and 200. For the 2N247 gain is 86. Anybody worked with these transistors before? Ever had oscillation in a Fuzz Face?Thanks, Charlie Luke
