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.
