How does a vacuum tube radio work
WebVacuum tubes have the same function as transistors. They are constructed like filament light bulbs. Inside an evacuated chamber, usually glass, they have glowing filaments and intricate metal screens and plates. The lightbulb-like filament is heated to incandescence to drive electrons off its surface.
