Since a long time I have a NAD C300 amplifier and I really liked it. It's simple, does (or must I say... Did) what it has to do and sounds pretty good.
But now, he's dead. It happened about a year ago when a leaking roof spilled some water into the PCB. First I heard a noise, like an overdriven sound, then the red LED lit up, what means the amp goes into 'protect mode' and then it failed completely. The two big (5A) fuses were blown and they immediately blow again when the amp is powered. When the PSU is disconnected, they don't blow so it is a short circuit in the main PCB, not in the PSU itsself.
I checked several Big SS-components for short circuits (still soldered on the PCB) and the two big 10.000µF Capacitors but I couldn't find a short.
Does any one have a schematic of this amplifier. I allready tried several NAD dealers and repair shops but I think they don't like to give away this information.
Without a schematic it's really hard to start looking because a lot of components were used in this amp and the faulty one(s) could be everyware...
