I believe you are correct they have the same pinout. Your post is very timely I just completed most of a 7051 checkout. Thanks to another Zone member for etching a board for me. Pic attached. Couple of things I want to change. I can say the circuit posted works, short of checkout of the sync circuit. I don't have the fet yet. Changes are clearance, I'm going to add a enable circuit, and a zener to allow the normal LM317 to be used.
