looks pretty solid... single-op for buffer (non-inverting?), could easely be modified as a booster, iso-out via (cheap?) 1:1 trafo. Dual-PowerSupply(+-15V) for OpAmp with DC-DC-Converter, which needs a 7805 in front. and a auto-gnd-lift-circuit?
looks usefull if the 1:1-trafo has some good specifications...
thanks for sharing ag!

Wow; that is nice of looking at PCB pics: you learn new things every day...........
Never heard about the NMA0515S but that really looks interesting: 5V in, + and -15V out. Sweet!
Nice to see the trimmer is replaced by a jumper; guess that is the difference between their booster and their buffer.
