All the parts in the other channel are in correct locations.
Removing the high side FET's brings the voltage down to 5.16vdc. None test shorted out of circuit.
Put new ones in and right back to full rail.

Reinstall the outputs and lift the drivers. Does it draw current when loaded or not?
If not, older the drivers back in and lift the next stage back and check for current draw when loaded.
Continue until you find the stage that causes the excessive current draw when loaded.
I'm assuming that you've checked the voltages for the driver stages shown in the schematic.

I removed Q112 and Q212 and both channels drop to 5vdc and under.
With these drivers removed niether channel draws current when loaded.

Reconnect those (work on only one channel) and lift Q109 and 111. Does the amp draw excess current when loading the speaker terminals?
Q109 and Q111 removed the volate goes down to 5vdc on the channel and it does not draw current loaded.
