Looking for a schematic for Kenwood KAC-8405 Audio Amplifier

[J_Wale05]

So I have a Kenwood KAC-8405 4/3/2 Channel Power Amplifier. I believe by looking at it that it is a Class AB amplifier that is pushing 720 Watts (max power) and the RMS when 4 channels are being used at 4 ohms it will be pushing 60 Watts to each channel. I am looking for a schematic or service manual for this amplifier to repair it. I tested it and something in the power supply section is blown but i need to know what components are being used so i can fix it as part of my project in my troubleshooting class next semester.

Thanks in advance to anybody i greatly appreciate it!
