Anybody tested this circuit? I have all the parts and i need your advices. I want to use irfb4227, with +/-100v or 90v. This circuit will be able to provide 1000w in 8ohm? Thanks.

Hi Dzony988,

yes I'm using LM311 and its a carrier based class d amp not UCD(self osc).fsw=250KHz or you can change fsw and no noise issues. if you want it PM me

Hi red_zone003,

That will not work. IR2110 high and low input change it will not switch. so don't go
