I need the electronic schematic for the Advent subwoofer model number ASW1200. I believe the power transformer is bad (no secondary voltages) and I think the filter capacitor on the 110VAC input line is shorted. I need the part numbers or the values, voltage ratings, and current (transformer) for both and was hoping to get the schematic for the powered subwoofer. Please send info to rjbrown5@verizon.net
