Identify motorola transistor

(1/3) > >>

Cyclotron:
I bought an electronics workbench on the FB marketplace and found some old components from when it was used at a GE factory.

I've been attempting to identify these transistors in the attached image, but so far, no luck.

Does anyone recognize them?


fzabkar:
Could it be this?

Probably not, as that is a Germanium transistor in a TO-39 metal can package.

It's possible it's a house coded generic part, labelled for GE.

Benta:
Certainly custom marking. No telling what they are.

We would commonly have them mark parts for us where I worked.   I too suspect this is what you have.  We would do this even with standard parts.  It may be a common part. 

Start by checking if they are NPN, Darlington...

Case is not the common EBC and I doubt they made too many TO92 case style 14(?).   Download a copy of their old 1980's small signal transistor databook.  Search for the case style.   Should narrow it down pretty fast.   If you can't Google find a databook, let me know as I am sure I have a PDF somewhere.   

In the end, do you really care?  Do you have a few reels or something and you have a need?
