Does anyone know of a method of either locating or finding information
about transistors that were manufactured in 1972? I am specifically
interested in locating or finding info on two transistors; their codes
a 2N5809 and 2N9614. I can't seem to find any supplier that has them
so I am presuming they are no longer manufactured. Thanks for whatever
help you can give me.

It might help if you told us why you want to know. Repairing something?
Building an old kit?
