I have been given some old transistors which I can't find specs on, not
on the net and not in any of the books I have access to.
First is a silicon NPN in a TO-66 case, marked 43A175954P2 (Motorola)
Second is a germanium PNP in a TO-36 case, marked '108'.
This is from an old IBM mainframe computer from early 1960's.
Then another TO-36 Ge PNP, marked 6840-2 (Motorola)
As these Ge power transistors are rare today, I could perhaps use them
as replacements in old equipment I have.
However, I do not know Vce max and Ic max, help is appreciated.
