Just switched it on this morning and - nothing. I've only had it since March It made a slight noise when I turned the power on (but just the usual noise it always makes i.e. of an electrical component coming to life) and then it just died. I've changed the fuse in the power supply, but nothing. I'm thinking maybe I turned the preamp on with the power amp already on. Would that be enough to kill it though? I always turn the volume right down before powering up and the PrimaLune auto mutes for a minute... Guess I'll have to speak to the dealer tomorrow. Hopefully they can sort me out, but I could do without this hassle.
