I have a Belva BB3000D V2 class d amplifier. The amplifier will play audio ok, but goes into protect at higher volumes. I do not have very much experience with Class D Amplifiers. I was unable to get a schematic from Belva. What should I be looking for. Any help would be great, thanks.

I have been trying to make a schematic, so some things might be wrong. Also I don't have all the cap values figured out yet. The amplifier go into protection mode at an increased volume. When this happens C94 gets charged up and disables the TL494 until the cap bleeds down. I'm not sure but I think the 2L or G1 is turning on the protect circuit.
