I have a concept amplifier in for repair with a blown powersupply. The audio section seems to be intact. All audio outputs check good with diode check. I rebuilt the powersupply and powered it up through a limiter. Powersupply seems to be stable. The audio section or rails stat to charge up and the amp goes into protect. Once it goes into protect the rail voltage on the outputs begins to drop. I did find to burn resistors bear the rca connector and LEDs that measure around 91 and 94 ohms so I am guessing these are 100 ohm resistors. Do these resistors being out of tolerance cause the protection circuit to trigger or could it be because of the current limiter?
