The Vacuum Tube Audio Frequency Power Amplifier Variable Amplitude Clipper provides a new method of varying vacuum tube power amplifier output power/volume to the loudspeaker. The amplitude at which power tube clipping occurs can be varied allowing one to take advantage of the inherent volume compression and output limiting at different volume levels. It reduces power tube plate voltage with minimal effect on preamp and driver tube voltage. Tone remains constant and the feel enhanced.
