This issue has bee posed many times already, I know. A friend has a pair of KSP-400 and one of them is making a loud hum / buzzzzing. I told him that if I can get hold of a schematic of the speakers and amp, I'd be more than happy to repair them. Tracing out things to created my own schematic would be very time consuming and I do not want to do this if I don't have to. So, does anybody have a PDF of the KSP-400 schematic they could email me? I have e-mailed Klipsch support twice requesting a schematic but I have yet to receive a reply. Any help in this regard would be appreciated. Thanks, Paul Stiles stilespj@spamcop.net
