I'm building a dual regulator and I want to beef up the current capability using pass transistors.
I have a good schematic from rason.org that shows how the transisrors are connected to the positive regulator chip.
But I can't find a schematic for how to connect the pass transistors for the negative regulator side.
I'm still unable to post diagrams here, they show up as a red x, but here is the regulator I want to beef up:

and here is a ciruit for the positive side:

Could I simply switch the PNP and NPN transistors, and connect it that way, to the negative regulator, or would I connect it an entirely different way?
Thanks for any responses.
