#355 Let's try to build a Vacuum Tube Radio

Vacuum tubes are an old, but fascinating technology that was used before transistors were invented. We can learn how simple circuits were back then if we build a kit like this three-tube receiver. Join me on my discovery journey. I have no clue about what I am doing. But, after the video, we will know more, I am sure. Whether the receiver will work or not.
