Vacuum Tube FM Radio — I Built One and Here’s Why It Works
Most DIY FM radios today rely on transistors or ICs. In this video, I built an FM radio using a vacuum tube and tested how this tube FM receiver performs in real-world conditions. This is not a nostalgia project. It’s a practical engineering experiment to understand why this design still works, what actually affects FM radio reception, and ...
