My NAD C300 amplifier has gone wrong.

At any volume, the sound is very quiet and extremely distorted. Have tried connecting it to several different inputs and sets of speakers.
There is no sound at all coming from the headphone socket.

Had a quick chat with the guy at my local HIfi specialist. He said any repair is likely to be £85+. I know that's more than the unit is worth. (Also they're not taking on any repairs at the moment).
Would it be worth opening it up myself to try and work out what's wrong in there?

It is part of my old/second system, so not a huge problem. Just seems a shame to bin it.

I don't know about the problem, but if it turns out it's broken put an honest description on ebay with a couple of photos and you'll sell it for a few quid. I've sold lots of broken old kit I thought nobody would want for £5-£30 + postage, and you know it will see another life repaired or as spares.

Could be pre amp stage if this unit is not merely a block amplifier.

Dear Parabola,

yes it's dead - IIRC the symptom is a classic sign of the output stage being kaput. What you're hearing could be the output driver stage trying to drive the speakers without the power trannies doing their thing,

regards,
Jet

That all sounds about right.

Looks like it's going to be an eBay 'Spares & repairs' entry then!
