At 1 kHz the requested output is about 1 V peak into 100 Ohm, or 10 mA peak load current. The complementary follower is inside the op-amp feedback loop, so crossover and VBE errors are corrected while loop gain remains available. Plot V(DRIVE) and V(OUT): DRIVE supplies the junction level shifts while OUT follows the closed-loop command. Inspect QN/QP currents around the zero crossing.
