These are electronic switches - but any time I switch from AUX to one of the other inputs, it immediately switches back to AUX. If I hold the button down for one of the other inputs, sound is fine.
Complicating factor: this is a UK C350 that I have been using both in the US with a transformer and overseas. Just back from Europe again, this problem cropped up about 30 mins after reinstalling the amplifier with a transformer that I have used successfully in the past. None of the other 220v units that are running off of this transformer seem to have a problem.
Could this be a blown fuse or a broken connector?
Hey,
I have noticed that this nad c3xx series may have a general problem with the input switching chip. There are more post here on fixya where people have similar problems as you have.
For a few year ago, I repaired a fault that had close to the same symptoms, it was a cambridge azur xxx amplifier, in this cambridge it was a defect smd component that they used as a input multiplexer.
I look forward to repair this fault in the future. Nowadays i alway collect schematics and create repair e-books and/or repair movie guides in the fault finding process.
