1. Mains Input: Accepts 110V/220V AC. It passes through a fuse and a mains switch.
2. EMI Filter: A line filter suppresses high-frequency noise from entering the audio path.
3. Toroidal Transformer: The heart of the unit. It steps down mains voltage to low voltage AC rails (typically ±45V to ±65V AC).
4. Rectification & Filtering: High-current bridge rectifiers convert AC to DC. Large filter capacitors (typically 10,000µF to 15,000µF, 63V-80V) smooth the DC to provide stable rails for the output transistors.
