    ASTATIC - CAD1036A 435790000 PreAmp PCB.

    The trusty MC33178 (and its quad version MC33179) is a reasonably powerful part (up to 80 mA source, 100 mA sink) with usable GBW and slew rate specs (5 MHz, 2 V/µs) that runs at a puny 420 µA per amplifier. It is particularly recommended for telephony applications, and indeed, a unity-gain follower driving 20 kHz at 2 Vpp into 600 ohms at 0.024% THD sounds hardly awe-inspiring. The npn-only AB output stage isn't too bad, but its symmetry is inherently limited, and it would have to be running at very small quiescent current. Performance should much improve with a few mA worth of Class A bias. The emitter follower on the sourcing side seems more trustworthy than the common emitter circuit on the sinking side, as it would always keep compensation capacitance well away from the outside world and seems to have slightly lower output impedance as well.
