A glass or metal container that prevents air molecules from disrupting electron flow. Common Types
Include additional grids to improve efficiency and reduce signal distortion.
Heated (white-hot) to "boil off" electrons via thermionic emission.
Positively charged electrode that attracts the electrons.
Placed between cathode and anode to control the volume of electrons.
Introduced the grid for amplification.
