Re: Ground loop hum question

A two wire line cord is grounded thru the neutral (white wire). All circuits must have a ground, as ground is the other half of the circuit. The 3rd wire 'safety ground' should be a quieter ground since their is normally no current flowing on it. Ground loop hum (60 Hz.) is usually caused by a problem in your ground system, altho defective capacitors can also cause hum. Check also for 'cold' solder joints, which usually look dull and gray instead of shiny.

Happy Listening !
