Hey!
So, I've been trying to make a symmetrical supply from an unsymmetrical for quite some time now, and I think (or at least hope) that I got it!
Problem is, I don't currently have any MOSFETs and ordering them will take some time so I thought, "Why not just ask?".
So I attached the schematic, so please check it out. My train of thought went like this (hopefully you can correct me if I went wrong somewhere):
I can make a normal resistor voltage divider using and buffer it with an op amp, but the problem is, the op amp can't source/sink enough current for, for instance, a modular synthesizer.
So, can I buffer the buffer op amp? I looked online and found a circuit similar to this, briefly simulated it and all seemed good

.
Thanks for the help guys!
