BC10[x] silicon transistors in fuzz pedals

Ro_S · Post by **Ro_S** » Mon Mar 31, 2014 12:14 pm

I've recently acquired a fuzz pedal with two BC107B transistors in it. I'm assuming it's probably some kind of Fuzz Face variant. It has about the same number of components.

Anyway, I've not encountered BC107s before, only BC108s and BC109s.

So what's the difference between BC107s, BC108s and BC109s, please? Is there any? Or is it only the A, B or C suffix of the transistor code (indicating gain amount?) that's the important, distinguishing thing?

thanks

Looks like there's a lot of small differences in gain, noise and such, between both the part numbers, and the letter suffixes afterwards.
