Vacuum Tube System
A vacuum tube system uses sealed glass tubes containing electrodes to control electrical signals. When powered, these tubes amplify or switch electrical currents, acting like early electronic devices before transistors. They operate by creating a vacuum inside the tube, which allows electrons to flow freely between electrodes, enabling signals to be processed, amplified, or converted. Vacuum tubes were essential in early radios, computers, and television technology and laid the foundation for modern electronics development. Though largely replaced by solid-state components today, they are still valued for certain audio applications due to their unique sound qualities.
