Houston...we have a problem. I was just told by the person in charge of tech support at Classe that he believes only one or two manufacturers inthe workd mae a fuse with the specs required by the CA-2300. He said it wasn't enough to just get a 12 amp small, slow blow fuse....that it had to be particular type of "breaking capacity." He said he was only aware of one manufacturer of this type of fuse: an outfit called "Littlefuse. " He predicted that I'd regularly blow my amps' fuse unless it were able to handle the amplifier's massive current intake. When the 2300 is fired up, it is known to dim house lights because of the rush of current. Think I may sit this round out...unless someone has tried this on their own 2300.
