Vacuum Tube Link

Positively charged electrode that attracts the electrons.

Placed between cathode and anode to control the volume of electrons. vacuum tube

Examples include "magic eye" tubes for signal display, thyratrons, and magnetrons. Key Technical Details Positively charged electrode that attracts the electrons

Introduced the grid for amplification.

A (or thermionic valve) is an electronic component that controls electric current flow within a high-vacuum sealed container. Primarily used in early electronics, they amplify, switch, or regulate signals by controlling the movement of electrons emitted from a heated surface. Core Components converting AC to DC.

Include additional grids to improve efficiency and reduce signal distortion.

Basic rectifiers, converting AC to DC.
