YOu have somje RFI if you can hear radio through your system. Some Phono stages are prone to this. The 47Labs is one in particular. Where are you hookig the ground/drain wire to on your turntable?
Grounding problem: I'm clueless
Hi folks,
I'm getting a serious buzz/hum through my speakers when listening to vinyl.
Equipment:
-Kenwood KD500 w/Rega RB300 arm and Grado Gold MM cartridge
-Antique Sound Lab Mini Phono tubed phono stage
-Audio Aero Prima hybrid integrated
-Silverline SR15 monitors
The previous owner of the phono stage attached a ground plug to the outboard power supply, he said it got rid of the hum for him. No such luck here. I've tried running a ground cable from the turntable to the preamp, and from the turntable to the power supply. It's quieter when attached to the power supply, but still not really acceptable.
Some more info: power is being filtered through a Shunyata Guardian. Once in a while I'll heard a very faint radio signal through on of the speakers. Not sure if any of that matters, but there it is.
Any advice would be much appreciated.
Thanks!
