Hello all,
I've got a unit here that goes into protection a few seconds after power up. I've got NOTHING connected to it, and the volume all the way down. The output transistors all ohm-meter OK. The +/- 45 rail (approximate) seems OK. ALL 5 channels have about +25V on them, which explains the protection, and indicates some sort of power supply issue. Any ideas?
I don't have a schematic or service manual for this unit. Thanks for your time.
