Sugden Sapphire FBA-800 Pure Class A Power Amplifier

FBA-800 is Sugden's most advanced power amplifier. The floating bridge design combines four 20 Watt amplifiers in a single stereo chassis. Each channel consists of two amplifiers working as voltage amplifiers, driving an output stage of bridged power transistors. The advantages are a low noise floor, better power output relative to the voltage rails (x2) and a fixed current class A mode enabling low output impedance and better load tolerance.
