2x100W LM4702 Audio Amplifier is based on the dedicated driver from National Semiconductor, which drive 2 pair of power transistors. Each channel is using a LM4702 + one pairs of power MOS-FET transistors 2SK1530 and 2SJ201. Few electrical characteristics are: Operatin Class A or B (can adjust if needed into Class A), Output power: 100W at 8Ω for
