A standard reverse-engineered breakdown of the WX-DC12003 circuit schematic contains three distinct operational stages:

The "front end" of the schematic handles the incoming power. Converts AC input to pulsating DC.

She turned the schematic toward him and pointed at a tiny symbol near the power inlet — not a standard engineering mark. A triangle inside a circle. The same logo she’d seen on files from the , a black-budget program officially shut down in 2003. Unofficially? It had never stopped. It had just gone deeper.
