Help w/ Class D driver

[Tom7227]

I am working a DC Audio 12K amp, tring to get a handle on the problem. The amp isn't in protect, all rail voltage are there. No oscillation...

Has any body seen this type of class d driver board, or could possible help identify the IC that are ground off,

Thank You

ive never seen that. can u get any voltages off the pins of those ic's?

look like mosfets.
If theres a number of pins connected together ie. 3 then they are probably single devices.
If there a 2 x 2pins connected, they are probable dual

It's likely 2 op-amps (or one op-amps and one comparator) and a driver IC like the IR2184S.
