+/-12V 5A, 100W filterless class D

The intended circuit looks like this. Does anyone see any problems? Power supply is well capable of 5A.

30V peak is actually a little more than 100W into 4 ohms. Prms=Vpeak^2/(2*R)=112.5 W. If somebody doesn't know these elementary calculations, then I suggest him not to build any amplifiers.

But for those who are capable of designing something (and have good soldering skill), I recommend TAS5162 or similar power stage for this power level.
