I've got a rackmount 2 channel ART tube pre, and a pair of small ART tube

Likely not the tubes, could be bad wiring in the unit, flaky power supply,
etc. What is the unit plugged into? Power conditioner? Power strip?
Directly into the wall? Did you try different places to plugin to rule out
any issues there?

This is related to recording, and my recordings are made on linux, so,
it is tangential to all of these lists. :-)
I own an ART tube pac, which is a preamp compressor combo unit.
It is the first generation of this unit I believe. I've just started
using this unit.
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 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. =A0The hum is audible in silences on
my tracks, so I know it's not just my playback system.
Now, before you go on about how the ART pre is cheap and crappy. I
know it's a budget pre, that's why I can afford it. I'm only lo=
