What to use these for. The easiest crossrefence to find is the nte199.

Are these "A", "B", or "C"? These denote the gain range. "A" are <100 Hfe, and "C" are >200 up to 600! The max collector current is 100mA, and the Vce max is 20V. The Ft is 100 MHz. They look like they'd be good in an AM transistor radio!

C versions.
am radio...eh..not for pedals I take it.
Okay, I have no attachment to parts.

You
could use them in almost anything, but they won't be particularly quiet if you're trying to get lots of gain from them (I wouldn't use them in a Big Muff, for example), but in a low gain circuit, they'll be fine.

Isn't this question a bit like: I found some tubes, what amplifier can I build from this? Or: I found some wheels, what car can I build. For transistors, only type and gain range really matters, I believe...

Except maybe for the noise as mictester mentionned, and also the current available (?)...
A search here gives a
thread about a pedal using some...

You could build every pedal Zvex has ever designed with that many bs170s couldn't you?

B
S170 aren't B
C170...
Was it a joke?

Thank you mictester.
Everybody else....
