I found with Irfb4227's I needed gate drivers.
The amp played ok until I turned it up then it would start resetting.
Deadtime and OC were at max setting so they should have been OK.

Well done getting it working on stripboard, I struggled using a tightly laid out pcb !

I used T106-2 for core.

Does it play to max volume without resetting ?
That's the best test.
