.....when repairing or cloning old fuzz units one often needs
germanium pnp transistors, sometimes with a gain of 200 or so.
These have pretty well dried up, and the germanium specialists
are pretty pricey....so i wondered if anyone could think of a way
to make a 3 terminal drop in equiv. from current parts? the
crucial thing is the softer knee of the characteristic curve.
No, but... A friend of mine insists that the NTE (that's a readily
available line of "replacement" transistors) NTE123AP transistor works
remarkably well in a Fuzz Face circuit. So we tried it; literally
soldering aligator clips into the Fuzz Face circuit board and
connecting up, oh, I dunno, maybe 60 different transistors, and sure
enough, these really sounded the best.
I have no explanation for this.
