RE: VK-3i hum

Posted by SpotcheckBilly12345 on February 17, 2017 at 09:08:26:
Have you tried disconnecting your cable modem from the wall outlet? Just because it's not directly connected to your preamp doesn't mean that they don't share ground circuits considering that both outlets are in the same room. Cable modems are notorious for causing hum.

What's it gonna cost you to try it?

Cheers,
SB
