It sounds like there is a problem with the differential circuit. The bias I am not sure about, as every unit is different. You should get the service manual to be sure or call Denon and see if they can give you an idea. Good Luck

Look for shorted output transistors or possibly shorted rectifier diodes. An immediate fuse blowing up usually means that the power supply is the problem. Keep us posted.

There is apparently some component in the stanby circuit that is malfunctioning. There may be a milli amp fuse off the standy transformer secondary. Check - don't confuse with a resistor. It may read 2 ohms or less
