Hi people!
Amazing amp project!
I was wondering if this could be used as a guitar power amp. I've already made a tube preamp for the warm sound, but I want to make a class D power stage for it. Could this be possible?

can you parallel output of this amp to use three pairs output? or has any one tried it with success?

To be honest this class d really aint any simpler than my latest work, though performance might be better even though i generally dislike P channel fets because they never match the N channel in on resistance and current rating.

i very much agree with you p channel is a hustle but i am taking the cost of ic ir2110 into consideration i hope you design was a discreet one.
>>>> i wanted to make the amp more stable by paralleling the outputs.

I'm currently creating a pcb layout for this, all through hole and easily obtainable parts.
I added low side current sensing and speaker protect in one board. Also added parallel diode/gate resistor to match P and N channel gate charging.
