About the Challenger 115

The AudioValve Challenger 115 mono amplifier is a high-end Class A tube amplifier designed for audiophiles seeking powerful and transparent sound. It delivers 115 watts into 8 ohms using a parallel push-pull configuration with six beam power pentode tubes (EL34, KT88, or 6550), supported by driver tubes 2 x 12AU7 and 1 x 12AX7. The amplifier features a revolutionary Automatic Bias Regulator (ABR) circuitry that independently monitors and controls each tube's bias, simplifying tube replacement and eliminating the need for tube matching. It has a frequency response from 5Hz to 40kHz, total harmonic distortion of 0.3%, and a damping factor of 5. The amplifier supports speaker loads from 2Ω to 8Ω and has an input sensitivity of 0.775V. Its robust construction includes a plexiglass top for easy tube access and weighs 25 kg with dimensions of 430 x 280 x 240 mm. The design emphasizes musical authority, transparency, and beautiful tonality, making it suitable for demanding high-fidelity systems.
