Top-class mosfet power amplifier based on the Renesas SK1058/SJ162 mosfets. The amplifier is capable of delivering 100W in 8ohm at very low distortion and noise levels.

More information on the design can be found in the Mosfet amplifier project page.

Specifications:

• Max output power: 100W@8ohm, 150W@4ohm
• THD+N (1kHz): < 0.003%
• Noise level: < -100 dB
• Input sensitivity: 1.2V rms
• Input impedance: 22kohm
• Bandwidth: 100kHz
• Voltage gain: 27dB
• Slew rate: 15V/us
• PCB dimensions: 100x60mm

Mounting instructions are provided under 'Downloads'. To build it a proper heatsink is needed (depending on supply/load).
