I will post the partnumbers.
I have a AAB 11800 defective here, but with replaced both driver IC's and 4 gatedrivers and mosfets, it started up with clipping led on. Railvoltage will come on after about 30 seconds, so check also the duty cycle of the gate of H3 power supply mosfets (just small peaks with the amp I have..). The systemcontroller (PIC 16F1828) is defective or see some wrong inputsignals.
All low voltage power supplies seems te be ok.
