Don’t want to be that guy but why is this trending on the front page? This is a very basic rudimentary page a particular transistor - nothing interesting like Ken Sheriff’s analysis or Ben Eater’s videos.
To pick just one example, Philips Semiconductor disappeared two corporate reorganizations ago, and was never all that interested in making the 2N2222... they have always preferred the BC series.
And the guy's name wasn't "Wlater".
I'll stop there, lest my blood pressure rise too high.
This should not be on the front page. It's garbage.
