I can't see any protection circuit.
First step is to identify the cost.If isn't near the commercial one, maybe i will give a try.
Is this a tested or a beta version?

here is a final version of APEX regulated PSU made fine tuned with transformer snubbers and the premium wago 256-402 connectors for the o/p. The layout is single sided and can be etched at home. Or can be produced at boardhouse as a 2 sided layout.
regards
Prasi
