Description
If you hear somebody talk about valve, they're the same as tube. “Valve” is an English term, while “Tube” is an American term. They both refer to the vacuum tube/valve in an pre-amp/amplifier/microphone. A valve amplifier or tube amplifier is a type of electronic amplifier that uses vacuum tubes to increase the amplitude or power of a signal. Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers in the 1960s and 1970s.
