Probably why they didn't have a ground terminal for power.
Audible noise? I know this is not LD related, but I'm getting a buzzing sound when I attempt to digitize my vinyl. When I touch the ground lug on the turntable it disappears. I'm still confused why there is a ground lug on a turntable as the turntable and amplifier power cords only have the two prongs (hot and neutral, although hot and neutral are tied together at the breaker box). Plus my house was wired before they had ground, and the boxes that hold the outlets in are plastic so I know they didn't ground that. I did add a few outlets in my house and ran a ground from the breaker box to those particular outlets. So thinking I could get rid of the buzzing ground noise I made my own ground wire that runs from the turntable to the ground prong on the newly grounded outlet. That made the buzzing worse.
I'm wondering if the outlet where my computer is plugged in needs to be grounded? As my set up is: turntable to ART Phono Plus (usb computer interface. This device also has a ground terminal which in the past I tied to the turntable ground) to my computer to record. Maybe the ground on the ART is relying on the computer ground since that has the computer has a three prong cord. Although in my situation there is no ground at that particular outlet.
