Buzz/Hum from Cary SLI-80
When I turn on my Cary, a electronic hum is immediately audible. It does not increase in volume when I increase the volume control. It is not loud, but distinct. When I turn on the CD player, the hum remains. When I play a CThe hum is present in either Triode or UL mode. The Cary is plugged into a PS Audio UPC 200, which is plugged into silver outlet in wall. This is not a big problem, but shouldn't it be dead silent when I turn on the Cary? Could it be the tubes? Any suggestions welcome. Thanks
