[sdiy] Non-inverting output buffer

[nicolas]

The other scenario that we want to protect against is having two outputs accidentally interconnected and fighting one another.  I am guilty of doing this from time to time when patching without thinking/looking.  A bit less likely, but on a +/-12V synth we could even have +/-15V being fed in from another synth in the next rack over.  

Do larger values of R1/R2 help prevent damage in this case?

Cheers,
Nicolas
