“gone obsolete” announcements induce sadness. Sometimes feels like a close friend has gone, sometimes like a colleague, or a neighbor, has moved to a distant second-source world.
Thus, the component vendors should always address the issue with a certain delicacy… Someone may feel hurt.
Anyway, it makes you feel a click older, when a component you loved to use at your youth, goes obsolete. I do not even dare to check the status of BC109 or 2N3904…

Have a nice weekend all!
