High speed low impedance PSU board bare PCB for preamp/headphone amp !

This is the bare board of a PSU board. The board features many filtering capacitors ( 92 pieces in total) connected in parallel on each power rail such that a high capacitance and low impedance can be created. For example, if all the capacitors are of 220uF, then there will have more than 22,000uF of capacitance and on each rail 46 capacitors are in parallel to reduce their ESR substantially.

The board is very suitable for preamplifier and headphone amplifier, or the driving stage of power amplifier.

The board surface is gold plated.
