"Class A refers to a high performance style of circuitry used in vacuum tube audio devices to extract maximum efficiency from power tubes. A constant high voltage signal is sent through the power stage without the forced negative feedback (or "cool down cycle") inherent in the Class A/B design. Matchless amplifiers rely on superior design, construction and components to manage the power of true Class A operation. Matchless Class A amplifiers provide an "alive" response, true tone, rich harmonics and smooth transition into distortion. "
C'est des cathode biased, certes... mais bon
