Hi? Joel,
Your are same with my result.? I have took out 1 turn form L1, L2 and L3. and my output power increase to ~2W? @13.8v I plan to experiment with replace MPS751 to Q6 this weekend and see how it change.

I'm a little hesitant to remove anymore for fear I will go the opposite direction.? I now have a little over 2 watts output at 13.8 volts, up from 1.6 watts. So I guess I'm just going to accept this, as I didn't really gain that much more power after the mods. It works perfect in every other way.
