I think the cooling fan should be temperature controlled an not necessarily voltage regulated. Audio amps spend most of their time at fairly low power levels so a cooling fan shouldn't be needed very often. Excellent job on the layout and design.

Thank you

You have an interesting way of driving the top FET in this design. I am not sure how the conduction timing is controlled to prevent both FETs being on during switching. I am thinking since it is transformer driven the top can't turn on until the flux starts to change in the transformer. Clever, if that's what is happening. Is this a common?
