The IS1000 has sold.
In great condition, works fine. But it has a buzz, not too loud, but can hear it in the quiet mornings here. It is 2 large toroids stacked one on top of the other. Might be a mechanical buzz that is fixed with damping between toroids or case? Or you could uh isolate it from the room behind something. It's heavy, shipping weight ~ 40lbs. , so I put a low price on it.
$125 plus shipping from 95521. Conus only.
