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.

It should run hot to touch at idle, about 120F, because it is MOSFET type amplifier.

look my dear try to first step make free run via 5802 sp 2- clean drum unit carfully throuh clean cleaner drum attention: free run make it 100 sheet but i don't under stand yo in last sentence ( fixed new dev toner

what i can tell you is that there is a comunication problem between the printer board and main controller. the only suggestion i have for you is to call for service and have someone come out and check all the boards. unless you know how to remove them and try putting them back in

Have it serviced. Do you know what GFA stands for. People at Adcom do have a great sense of humor. Take it only to a high end audio servicer. Contact Adcom. This is good stuff you wouldn't want a hack working on it.

Running an amp in bridge mode requires a specific circuit design. It is not possible to combine 2 amps in this fashion.

Remove the output transistors and measure each of the sets of 3 pads and report the voltage readings here. I suspect that you have either a blown driver circuit or output transistors. The voltage readings will give me an idea on where to start looking for specifics.

Thanks,
Dan
