Can someone draw me a diagram labeling the pinouts for a PNP Germanium transistor.  I am using these for the ColorSound ToneBender MKII Pro and im not sure where to put the transistors in.  I have 6 of these, because I am building 2 of the ToneBenders.  I have the values of each if thats needed.

It developed into a wealth of info on trannies!

DIY FAQ link.

Near the bottom are transistor pinouts.

Actually, most of what people ask can be found in there or using a search.

  DMM Hfe checkers do the pinout verification thing well.
  Usually just turning them around once in the socket, PNP side and NPN side too...you probably won't have to twist two of the leads around to get a reasonable reading which shows pinout and polarity, a 'reasonable' [not accurate for calculating gain] Hfe reading.
Convention creates following, following creates convention.

... got a couple of OC170 here and i wonder how to use this pinout? is the shield only to be discarded or what?
... just standing on the shoulders of the diy stompbox scene out there.

OC170s can suffer from tin whisker syndrome.
