TRANSISTORS: RG Keen, Germanium Transistor Test Method
If you haven’t heard of this before (which seems unlikely), here’s the original RG Keen article, which explains how it works. I use a spreadsheet set up with the calculations ready to go for testing; there’s also an online calculator here. NOTE: Be prepared to see the voltage fluctuate a lot while the transistor stabilises. Don’t wait too long though, … Read more
