*Power absorbsion with amplifier switched off is not zero because to comply with EN60065/IEC 60065:2001-
12 all amplifier circuitry must include a “bleed” resistor across the incoming AC mains power to discharge
residual current to prevent the risk of shock from an amplifier disconnected from the mains.
