Hello everyone ! I have this corzus md3000 amplifier that writes FALL on the display. I checked all the mosfets of both the pwm and the power amp and they are ok, the amplifier uses some irs2092 that I replaced and I also replaced some optocouplers! Do you have the schematic for this amp? I searched the internet but couldn't find anything! Thanks and good job

doing an analysis I noticed that the current filter coil that feeds the final stage was damaged and a feedback track of the pwm was also damaged! so I took the coil apart and rewound the copper and the amp started up again!
