A vacuum tube is an electron tube that controls the flow of electrons in a vacuum. It is generally used to amplify a signal by controlling the movement of electrons in an evacuated space. The electronic era began with the invention of the vacuum tube which were everywhere to be found in the early generations of electronic devices, such as radios, televisions, magnetron, klystron, photomultiplier, x-ray tube and cathode ray tube. Vacuum tube technology was essentially replaced with the invention of the transistor and the subsequent development of low-cost batch fabrication techniques for solid state integrated circuits. However, vacuum tubes have been still used as audio components due to their superior audio characteristics over transistor electronics. Various amplifiers utilizing a vacuum tube are proposed for applications of electric and electronics music instruments, audio instruments, etc.
