I have the same version amp and it is going into protect mode. I had to replace Q4-Q10 and IC5 because the owner fried these transistors and driver. I also found that R59 was burned so replaced that with a 4.7 ohm resistor. I replaced IC5 with the IR4427 but the amp still goes into protect and the fan runs.
I checked the speaker drivers which tested good.
Could anyone offer any insight into why this would still be failing to start? Does anyone have a version 2 schematic they would be willing to share?
Thanks for any help.
