Gar2520 Discrete Opamp

The Gar2520 is an imitation of the mid 70's API 2520 opamps designed by Gary Barnett and based on the Peter Lazaro's reverse-engineering work.  According to CAPI, the Gar2520 sounds "hairsplittingly" close to the original, while using all modern and widely available components.
