This is a blank (unassembled) PC board to build a high voltage linear voltage regulator. It is a floating “Maida” type regulator, using an LM317 and a high voltage N-channel power MOSFET. This is typically used for tube audio circuits, to create a regulated B+ or screen voltage supply from a higher B+ supply voltage.
