Basic Schematic Reading: If you're new to reading schematics, start with the basics. Understand that a schematic is a diagram showing the connections between components. Symbols represent different types of components.
The positive rail from C5 led to the primary winding of a large transformer, T1. But before it could enter the transformer, it took a detour through a small, three-legged component: Q1, the main switching transistor. The schematic showed a tiny clock icon next to its gate pin. That clock came from a black box labeled IC1 (PWM Controller) —a TL494. This was the heart. It pulsed Q1 on and off tens of thousands of times per second, creating a high-frequency AC inside T1. That was the secret: scream across the magnetic gap to shrink the copper and iron.
