    Cleaning house.
    Throwing out all the old transistors I've collected if I don't at least have enough to catalog.

    In my uj bin I've got some GE-687.

    Is there a quick way to find out if it's a uj or put?

    I'm too tired tonite to put (pun) a circuit together and can't find any other info.

    I'm off the hook.
    I found a note from my smarter self showing the pin-out and identified as a put.:)
