What is Tube amplifier?
[[File:SE-300B-70W.jpg|thumb|Tube amplifier]] A '''tube amplifier''' is a sound [[amplifier]] that uses [[vacuum tube]]s instead of [[transistor]]s to amplify signal. Some people think the [[sound]] from tube amplifiers is better than transistor-based amplifiers. Even the measured [[distortion]] would be higher with vacuum tubes. {{Commonscat|Tube amplifiers}} {{tech-stub}} [[Category:Audio technology]]
