Question about NAD S300 Amplifier
SOURCE: NAD S300 Amplifer humming
You have either got a bad earth connection, or possibily there's a capacitor failed.
If you can't find a dodgy conection, I would replace the large Electrolytic Capacitors in the power section, they are used to take out 50hz hum in the mains electric, when they go you get that hum coming into your system.
