Re: Harman Kardon AVR130 - Issues
Memory backup should be maintained by the battery, R777 and D783 are used during charging the battery, when the unit is unpluged, the battery current flows through D779 and Dd724 to maintain around 2.5 to 3 volts on C886 (VDD)
I believe all parameters are stored in the micro IC72
