Nice it looks like the power is more regulated, but the smaller componets and the resistors are limiting your current. Neuro's FET design is more effective and does not get hot at all. Warm but not hot. I think the transistors and resistors your have to regulate the power is causing the restrictive current output.
(At least it looks like small transistors setup in a regulate type circuit.) Post the part numbers of the smaller transistors maybe we can fix the heat problem. Post a diagram if possible. Oh are you using logic level Fet's.
