Hi my adcom 5802 get right Chanal not working . I don't know why every time I put 2 fuse for that Chanel is burn st thing look like diot ... And after that 2 fuse burn too

If I can read you right you are saying that the device keeps blowing the fuse?

Fuses blow when there is an overload. As it is an amplifier we are dealing with the cause is more than likely a shorted output transistor or more than one, or whatever does the main amplification for the device. These devices are located on the main power amp board attached to a heat sink. If the amp has fuses for each channel then you only need to replace the devices on that channel, with the fuses blowing on it. The cause of shorted devices is often bad speaker wires or them touching.
