VACUUM TUBE
Also called an electron tube vacuum tube or even light, is an active electronic component, generally used
as an amplifier. The vacuum tube rectifier or
amplifier has been replaced in many applications in different semiconductors, but to date remains irreplaceable in some areas
such as high power amplifier or
hyperfréquences.Les electron tubes means the components that use electrodes, placed in a vacuum or a gas,
isolated from each other in this medium, and comprising at least one source
Electron. Durable temperature isolates all from the outside. Although the envelope is usually glass,
power tubes often use ceramic and
metal. The electrodes are connected to terminals that pass through the passages sealed envelope. On most tubes,
terminations are designed to be pin
installed in a vacuum tube holder for easy replacement
