I am working on a Marantz SR-63U and the unit is in protect, ("PRE- ON" displayed on front panel, no speaker relay action) but has no DC on outputs. Does anyone have a manual in PDF format or an idea on what to look for? I suspect a problem in the protect circuitry, but we don't normally work on Marantz, so I am a little stuck on it. Any help would be great. Thanx. Scott Beebe Ohm Electronics Inc. 609 W.
