BRE1600.1D Audio drive problems

[Formas]

This amp was going in and out of protect even after replacing the damage output fets, the driver card is rebuilt primarily changing all the 1D's and 2D's and the P2D's. Its not going in protect now reproducing audio, everything is on ambient temperature but base on the scopings i think im having a problem with the drive waves (i think), i have attach the images.

Pull the rectifiers then re-check the output drive waveforms.

What's the 3rd image?

Ive figured it out, there was bad rail caps on the positive rail, ive replaced them and it smoothed out the drive wave.

That was when i probe the drain of the highside fets.
