4 legged germanium

[drgonzo1969]

I have these NPN germanium transistors I want to try in my dizzy elk pcb but the transistors have four legs in stead of three. It looks like maybe it has 2 collectors? How should I plug this sucker in?

Fourth leg is the "body". In some circuits, this is just tied to the emitter - try that first.

I'm not sure, but I think the 4th leg is ground. Pull the data sheet (although I suspect it's in Russian).

I believe it's attached to the body so no need for it in your application, chop chop!
Do you have a transistor tester, best way to check!

Just continuity check it to the transistor body they are normally ground if it beeps it's ground and you can just snip it off as @music6000 said
