Hi folks, 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. The 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 looking for constructive ideas, or similar experience. Thanks so much!
