No, the standard linear supply is just the same as before. The external regulator needs two supply feeds to do its job so its not just a "add on the end" thing. unlike if using a three pin reg, I could take advantage and design a regulator that didnt have to get all its supply from the one voltage source. So for (say) the 5v touch, the board will get a 8v high current preregulated supply, and then a 10v low current regulated supply to drive the error amplifier.

The pictures are of the prototype BTW, for the Touch there is no need to have the external connector on the base unit, it will be hard wired,
