Baby first Opamp Buffer / Preamp

[Razorblade]

After a long sleep this project is back alive. I found the PCB while cleaning up my lab. I am not sure about the power supply though, With all that capatiance on the rails .... i waned to use a didden super reg, any suggestions on the ps?

It seems a waste to operate a very high gain opamp at unity gain and the compromises that brings, when a unity gain buffer that is designed to operate best at unity gain gives at least equal performance.

The lme49600 datasheet shows tremendous performance.

The LME49600 distortion is quoted when it's inside of the feedback loop of an LME49710. There is no separate spec for the LME49600 alone.

And, this is the benefit of using a 50MHz gain bandwidth amplifier at low gains --> tons of feedback --> extremely low distortion.
