I found the problem the DB6 DIAC was also wrong in the PDC board.

The diac type is DB6.

Hi All, I have the same problem. It started with fuse blowing. What I found is one of the FET was faulty in the power supply modul. But after swap it to the same one the power supply still don't want to start. No fuse blow, but nothing work after the coil part. So it doesn't make any DC neither for feature module neither for AMP module. The AMP and the feature module is working I ahve tested. I want to swap the power supply to a similar one. Can you please measure the voltage output for the AMP module (the black and red wire toward AMP module)? Is it fixed or changing in line the input? Thanks,TamasM
