Valve Amplifiers

Valve amplifiers are audio amplifiers that use vacuum tubes to amplify analogue audio signals for playback through loudspeakers. Also known as tube amplifiers, they perform the same fundamental role as other amplifier types by increasing signal level and power so it can drive speakers. In hi-fi systems, valve amplifiers are used either as integrated amplifiers or as dedicated power amplifiers, depending on system design and component configuration.

Valve Amplifiers in Hi-Fi Systems

Valve amplifiers receive an audio signal from a source component or preamplifier and amplify it to a level suitable for driving loudspeakers. Integrated valve amplifiers combine preamplification and power amplification in a single unit, while valve power amplifiers rely on an external preamplifier or source with volume control. Many valve models are configured as integrated amplifiers, combining signal control and amplification in one chassis.

Valve amplifiers are available in a range of circuit designs and output configurations, using different tube types and power ratings. Selection depends on speaker compatibility, system layout and whether the amplifier is intended to operate as a standalone integrated unit or as part of a separates-based system. Valve designs are also available as dedicated power amplifiers for use in systems with separate preamplification.
