this is my first little contribution to the community. this simple board offer a voltage regulator for opamps (buffer, crossover, etc) and an antibump circuitry with dc output protection.
IMPORTANT:
the relay is connected as single channel, but the schematic is easily modificable to suit different needs (stereo output)
