pinout search

[birt]

I'm looking for the pinout of the GC512 and GC521 transistors. These are Ge's (PNP and NPN) made by Tesla.

there is no indication on the transistors, the legs are in one line, one pair and one a bit separated. Someone who knows these? (i bought 300 :p)

 Best I could find http://www.eca.de/html/GC/GC512.html
and... http://www.eca.de/html/GC/GC521K.html

Building a Germanium fuzzface with the GC521. I got some gold plated ones for a decent price. Too bad information on theese things are pretty rare.

I can confirm that on the GC521:
Pin 1 - Base
Pin 2 - Collector
Pin 3 - Emitter

seek out this datasheet:

http://www.datasheetarchive.com/dl/Scans-048/DSAGER000621.pdf

it doesn't list the GC521, but page 171 suggests the Tesla GC521(K) is equivalent to the AC187(K). so the pinout should be our old favourite TO1.

I usually just plug unknowns into sockets om my meter and try different orientations until i get a reading that makes sense. Aren't there cheap little naked meters out of China you can plug your transistor into and the screen shows/identifies all the particulars.
