Lawrence Audio preamplifier


The little known Lawrence Audio preamplifier: 

The vacuum-tube has second level regulation. It uses hybrid capacitors and push-pull output. It has a wider frequency and a greater dynamic range than the average pre-amplifier, giving the music a fuller feeling. It creates a greater dynamic without reducing the quality of the music. The reduced quality may arise from waveform compression during volume change. This pre-amp reduces impedance to one quarter.
