The Harman Kardon C-100 is a 100 W mono tube amplifier employing Ultra-Linear Williamson circuitry with generous inverse feedback for high damping factor and speaker connection flexibility. Designed for integration into audio systems requiring warm, musical reproduction with precise tonal control, the unit operates from 117 V, 60 Hz house current (105–125 V tolerance) and includes auxiliary AC receptacles for powering associated devices.

– Compatibility & Integration
Speaker connection impedance selection:
• 4–12 Ω: Connect between "G" and "8" terminals for maximum damping factor
• 12–24 Ω: Connect between "G" and "16" terminals
• <4 Ω: Connect between "8" and "16" terminals (bridged)
Tuner integration via shielded coaxial cable to tuner output receptacle rated minimum 0.5 V.
