Bi-polar Universal Shunt Regulator Board (PCB only, no parts)

The Bi-polar Universal Shunt Regulator Board contains a pair of high performance shunt voltage regulators optimized for audio use. It is suitable for powering hi-fidelity small signal audio circuitry. The Bi-polar Universal Shunt Regulator Board implements the design by Walt Jung that first appeared in Walt Jung's AudioXpress interview of 10/2012.  Bare board only. Parts are not included and need to be obtained separately. Assembly is required. This board is being sold with Mr. Jung's kind permission, but in no way it is endorsed or supported by him.
