    Hello there,

    I'm embarking on my first DIY Pedal, a Fuzz 69 type. It's a PCB kit, but I plan to eventually do my own stuff. Anyway..

    I got to the Germanium transistors and realized I don't which legs are what...

    They are NPN 2N229 Germanium Transistors

    if you look hard on that datasheet pic (the only one I can find here), you can guess ;)

    You can also google <whatever transistor>pinouts, it’s tremendously helpful. Works for ICs too.

    A 2N229 is an NPN transistor though and that layout is for PNP trannies.

    I’ve got about a dozen of those 229’s in original packaging and a couple of loose ones. I put one in a Rangemaster circuit a little while back. It’s not bad.

    EDIT: Oh, never mind. I just found your other thread and see you’re on top of it.
