I agree with Dave that Acoustic Arts' statement about most manufacturers not servicing used gear is likely untrue.
I have had used gear serviced by Lamm, Belles and VAC, and my impression is that many if not most US manufacturers will not only service used gear, but they may also honor the original warranty.
