Will double check, but I checked datasheets for every transistor going from the part no. on the casing. From memory all of them are what was specified in the BOM, no substitutions.

If I understand your design correctly, everything up to the fet gates is powered from the nano board 12V supply (via the bias supplies). Once the variable power supply is here I'm pretty keen to check the stability of all these supplies as output fet voltage is increased with the toroid connected, if current limited testing still shows problems.

Not losing any sleep over this, I'm usually ok at working this sort of thing out eventually and having the proper equipment will help.
