I stand corrected! Thank you so much Steve! I had disconnected the cable tv from the back of the cable box but when I pushed it back on its shelf, the cable was still in slight contact with the connector. I realized that if I removed the coax cable away from the cable box, the hum disappeared. Looks like I need to get a cable TV ground.
Loud Hum from DNA 0.5
I just had my DNA 0.5 serviced at McCormack Audio for a blown capacitor. Now that I have hooked it back up to my system, there is a loud hum in my speakers. This never occurred before. It doesn't occur if I unplug the preamp input cables and changing the outlet didn't make a difference either. I even tried another set of interconnects and that didn't make a difference either.
The preamp is a Yamaha AV receiver and it has no known issues. I have no other amp available to me right now to hook it up to verify that only the DNA 0.5 is causing the problem.
I'm hoping someone here can make suggestions. Where the amp is being used is not my primary residence. I use an integrated amp at my home and have no way of testing this in my personal system.
Thanks!
