Vacuum Tube
Welcome to the Vacuum Tube!
Fundamentals
In electronics, a vacuum tube, an electron tube, or valve, or colloquially, a tube, is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.
Types
There are a lot of different vacuum tube types, all with their own applications, characteristics and construction. This page lists the different vacuum tube types which are described on the resistor guide.
Applications
Vacuum tubes are used in a wide variety of applications. This category contains pages explaining various vacuum tube applications.
