Hi there, the power supply doesnt have either + nor - 45 volt power supply present. The other voltages are OK.
First question, for a working unit should there be +-45volt present at the output of the power supply or is there a possibility that it is switched off due to some settings on the amp?
Does anybody have experience in fixing the power board and can recommend where to look as I dont have a schematic.
I suspect that the fault is in one 8 pin chip: 5181 PQAC it gets the output signals from the SG3525AP but I could not find the 5181 anywhere.
Does anybody know what that chip actually consist of ???
