Germanium transistors?

[bancika]

Hi,
I've found a guy on flee market here who has lots of transistors I suppose are GE. They look similar to these, but with three leads.

Price for "larger" ones is about 0.1 euro (about 12c) and smaller ones are 0.05 euros (they all look new, gold leads). Anyway, can you tell me which ones are interesting for DIY projects (pedals, amps, etc) so I should know which ones to look for.
Tnx

  ...The ones that sound good...
  .. probably have low leakage and enough gain/not too much gain...
  Those look like "Si Cans', have you measured the threshold voltages on the B/E diodes?

maybe they aren't GE at all, I didn't know there are SI trannies that look like that...

..if you can find "numbers" on them, that'd help....

that being said, i'm one of those guys who, if i find something interesting, i'll "buy first, ask questions later"....sometimes that theory works, sometimes it doesn't...but at approx $.12 each, why not buy 20 or 30 and test 'em !

 Even the metal can 2222  si trannys can get interesting. I'd just scoop up a bunch of em, you never know. Even if they suck you can use em for clipping diodes.

The one with the 106 looks like some AF106 PNP Ge I have. hfe:20-30 leakage<5uA
Maybe AF139?
