HV power supply:

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

With a pair of 2 x 22,000 uF audio grade cap, 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 for sensing the output offset volt to provide system cut out and speaker connection delay on. High voltage and 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 two sets of speaker relay output pins were posted at each sides of the board. Color coded cables for connection to power amp are pre-soldered for you (not shown).
