Uses LM3900N four-opamp IC and two transistors to step up headphone output signal of AF power amplifier sufficiently to drive pair of electrostatic headphones without introducing excessive distortion. Total harmonic distortion at 1 kHz is 1% at 300-V peak-to-peak output, and dropsto 0.1% at 50-V output.-N. Pollock, Elec-trostatic Headphone Amplifier, Wireless World, July 1976, p 35.
