Anyway, I'm hearing a low level hum, sortof like a
grounding hum.
Does anyone else use the ART line of pres? Has anyone had trouble with them?
The unit uses 2 tubes and I'm sure they aren't high quality tubes.
Could a lower quality tube cause a low level ground hum?
The tube itself, no. The power supply, yes.
The unit has a grounded plug, and I can't seem to
get rid of the hum
by unplugging other components, but when I mute the unit through my
sound card, the hum is decreased. The hum is audible in silences on
my tracks, so I know it's not just my playback system.
Which sound card is the preamp connected to, and how (type of
input, cable, etc.) ?
