If the amp is totally dead then the mains fuse is most likely blown. You need to check after replacing the mains fuse that you have both channels working as it is possible that you may have blown the output stage of the channel on which the spades were adjusted. If that is the case then the amp will have to be looked at by a technician as, according to the manual, the amp does not have fuses on the output stage.
Why did my amp just crash and burn ?
I just installed a new set of AQ Robin Hood Zero cables. A little hiss sound from the speakers prompted me to adjust the spade connecters just a little on the amp. Then low and behold , the amp just cuts off and currently appears dead as a doornail.
What just happened and needless to say this is an absolute bummer.
