Hi, I just got an old AU9900 integrated amp. Being comfortable with electronics I was hoping to clean and upgrade the unit. However, I'm having trouble finding a service manual for this unit.What I wanted to do was to clean and lube all the switch's and contact's, install an IEC receptical for a good PC, replace the power diodes with Harris FRED"S and also replace critical capaciters. Can anyone out there give me some advice? BTW, I did the same thing to a B&O Beomaster 8000, used plenty of caig pro-gold, and had no problem.:confused: :confused:
