What is a Tube Amplifier?
A tube amplifier is an electronic amplifier that uses vacuum tubes (also known as valves) to amplify an electrical signal. It operates by controlling the flow of electrons through a vacuum in a sealed glass or metal enclosure. Tube amplifiers were widely used in audio equipment, guitar amplifiers, and radios before the advent of transistors. They are still highly valued by audiophiles and musicians for their unique sound characteristics and warm, natural distortion. Tube amplifiers are also known for their high power output, making them suitable for large speakers or headphones.
