This is from a friend. I wasn't sure of the cause. Perhaps:
- Ground Loop
- The wire connecting the computer to stereo needs to be shielded?
I have a question about my stereo. I get a hum through my speakers, most pronounced when using an attached computer as a source of Pandora internet radio. I decided the problem was that the receiver wasn't properly grounded. So I got a grounding wire and proceeded to look for an attachment on the back of the receiver. There doesn't seem to be one! It's a Yamaha RX-V663 receiver. Did I mis-diagnose the problem? Is it possible to ground this receiver? How do I find the attachment point?
