The Logic Off Topic list

I know this is sort of OT, but I'm having a problem with my Eurorack 2004A,
(although I monitor Logic through it, how's that?) and I figured someone
here's gotta remember some stuff from those heady analog days.

 I find that after the unit has been powered up for a while, it begins to
emit a high pitched ringing on the auxillary outputs (*outputs*, not sends -
as in bus B). I'm guessing the sound is around 6-12 KHz.

Is this something that's likely to be fixable (is it common in mixers?) or
is it just bad design?

I've also had problems where sounds being sent to the main outs bleed
through to the auxillary outs - but that is something I just put down to bad
design (but I mention it here in case it's related). ]

Damn, I *knew* I should have gotten that Mackie 1604.

Thanks,
