A valve audio amplifier, also known as a tube amplifier, is a type of audio amplification device that uses vacuum tubes (or valves) to increase the power of audio signals. These amplifiers were widely used before the advent of solid-state technology and still have a dedicated following among audiophiles and musicians today.
