I have a perfectly functioning Russound CAM6.6 unit here minus the remotes, which can be found in a package of 6 on ebay. I have no need for such a piece and can't bring myself to tear it up for parts. The cheapest I could find these online (also with no remotes) was $750 or so plus shipping......so let's say $500 plus shipping in the lower 48 states only, this thing is heavy.
