Hi, I noticed on the build you don't specify using a pad on the transistor and regulator, nor thermal grease.
My understanding was you are always supposed to use these as the regulator backing is not grounded and could cause a short. In fact in another DIY project I did, I damaged my power supply when I failed to use the pad and grease.
So, am I right in assuming that you have designed these boards NOT to need the grease or isolation pads on the regulators and large transistor?
Thanks,
Mike
