Accuphase A-80 Class A Stereo Power Amplifier

Accuphase A-80 Class A Stereo Power Amplifier The A-80 is a Class A power amplifier developed as a stereo amplifier version of our 50th anniversary A-300 model. Optimizing the 10-parallel push-pull power MOS-FETs in the output stage produces an output power of 65 W into 8 ohms, 130 W into 4 ohms, 260 W into 2 ohms, and 520 W into 1 ohm. Rigorous investment into new, cutting-edge noise reduction technologies has achieved a sense of presence and minute expression that rival live performances. The A-80 power amplifier perfectly fuses modern technology with the wealth of knowledge Accuphase has amassed in its pursuit of perfect sonic expression. 65 W into 8 ohms, 130 W into 4 ohms, 260 W into 2 ohms,and 520 W into 1 ohm large linear output power Class A driven 10-parallel push-pull MOS-FET output stage Instrumentation amplifier Signal input section with a fully discrete configuration for low noise Current feedback amplification topology Balanced remote sensing MCS+ circuitry High damping factor of 1,000 Large, high-efficiency toroidal transformer High capacity 120,000 μF filtering capacitors Power amplification section on circuit boards using glass cloth fluorocarbon resin Hold time switching function that changes the meter peak display time 4-step gain control Bi-amping connection and bridged connection switching Large speaker terminals connected directly to protection circuitry Speaker output protection circuit guards against short-circuiting Highly reliable MOS-FET switches with no mechanical Aluminum hairline finish top plate High-carbon cast iron insulator feet with superior damping characteristics
