LV power supply:

DC output voltage and current depends only on transformer AC supply.

With a pair of audio grade Nova 2x22,000 uF capacitor, the power supply was designed with a greater storage capacitance, result with a stable output at high current drawn and a low ripple noise. Using standard IC designed for system protection and speaker delay on connection. High current rectifier is installed.

To maintain the heavy current flow along those copper tracks, the only choice is a double sided PCB board with large conducting surface.

Two sets of DC output pins and speaker output pins were posted on each side of the board. Color coded cable for connection to the power amp are pre-soldered for you (not shown).
