An audio circuit I found online and have been playing with has an odd
design (to me).
It's op-amp based running off a (separate) +/-15v supply.
There are on board caps across the supply, which is common enough. 10 and
0.1uF in parallel. But instead of going to ground, they are wired across
the +/-15v. Does that do the job as well? Or serves a different purpose?
