JFET single stage pre-amplifer BOZ PCB

This is the PCB of a stereo preamplifier using only a single JFET per channel, reference to JFET BOZ. This minimalist circuit provides superb transparency that can excel most of the other preamplifier circuits.

PCB dimension: 14cm x 9cm. PCB thickness 1.6mm. This PCB serves both the left and right channels. The assembled PCB picture is shown for reference. The board includes rectifier and regulator circuitry. It only need to feed in an AC 18V 50mA to function.
