Archive version of my Twitch stream from January 19, 2021. I do tests on the fake TL074 chips unboxed in the previous stream to try to document what was wrong with them. This didn't go really well. I made some missteps in setting up the tests, my breadboard was flaky, and then I lost the oscilloscope screenshots that I spent all this time collecting (because of an issue with the USB key I was saying them on). So it all may have been kind of a waste of time. But, this is the stream, for whatever it's worth.
More info on the fake TL074 chips in the North Coast News Web log.
