Jim Dunlop JD-F2 Germanium to Silicon BC108C transistor conversion.
Hey Everyone,
Recently, my red Jim Dunlop JD-F2 Fuzz Face died and stopped working while I was in the process of doing some re-organizing of my pedal board so I could add my Boss MT-2 Metalzone pedal, well, my red Fuzz Face pedal actually didn't just suddenly stop working, it started oscillating and then stopped working, so seeing as I had been looking for a good excuse to convert it over to silicon BC108C transistors from the stock NTE 158 Germanium ones, I decided to go ahead and remove the stock circuit board and replace it with one that happened to have two BC108C silicon transistors soldered onto it.
It's a well-known fact that Germanium transistors are temperature-sensitive, and, while the stock JD-F2 circuit board does incorporate a board-mounted thermistor as a way of mitigating any temperature effects, I decided to just cut-to-the-chase and do the conversion to silicon transistors since they are far-less temperature sensitive.
The replacement Fuzz Face circuit board I used was one that came as part of a kit of parts I had ordered from a company in England, called Pigeon FX....if my memory serves me right.
I'll post a pic of the insides of my red Jim Dunlop JD-F2 Fuzz Face, which I took after the conversion had been done, and I'll also post a link to a demo I uploaded to my soundcloud account, so you can hear what it sounds like.
Here we go:

And a close-up pic of the replacement circuit board.
The two silver things with three legs are the two BC108C silicon transistors.
