Other Notes: "Block low-level DC voltage sitting on your AC power line that causes the power transformer to hum or buzz."
"This type of mechanical transformer hum may be caused if other devices on your power line, or devices on nearby power lines, use AC power asymmetrically. This quite common low level DC tends to make toroid power transformers hum and overload. The effect is often seen in products with toroid transformers, but it’s not limited to just toroids; thus, the non-toroid transformers can also hum depending on the level of DC voltage on the AC line." - Ava Hi-Fi
