This schematic is the application note of Hitachi for their lateral fet devices , although this version has different resistors values , the 47pF compensation is also at the wrong place as it should be connected between base and collector of the facing MJE340. You can add a diode and a zener in serial from gate and drain of the of the fets to provide some current limitation. Last edited by wahab; 25th December 2011 at 07:22 PM. |

All that is needed for this 50W/8Ω amplifier is a 3A fuse on the speaker out, 10V gate zener diodes, and a 85°C thermal switch on the heatsink.
