So I ordered a Aune T1 tube dac/headphone amp from Amazon a week ago and it finally arrived today. Stupidly, in my haste I plugged the power adaptor into the wall without thinking and bing bam boom, it shorted out and now i probably need to replace it. Luckily the power adaptor itself wasnt connected to the Dac/Headphone amp yet so all I need to do is replace the power cable. I'm not much of an electrician but my question is would I be able to find a replacement for this power adaptor locally or would my DAC only run with this specific power adaptor from the Aune?

The power input is a five core power cable socket and the specs on the power adaptor are input: AC 110V-50/60Hz and output: AC 15V-0-15V 1A. Any helpful advice would be much appreciated.

I don't think you will find a replacement power supply in NZ very easily, it's a centre tapped AC output which are usually only found with audio equipment. It would be possible to make one if you're into that sort of stuff, otherwise you're probably better off looking for a replacement on ebay or somewhere. There's also a possibility that there's a fuse that can be replaced if you open up the casing.

Just opened it up. Not sure what I'm looking at right now (looks like a giant resistor) but it sure smells like burnt plastic/metal. Thanks for the advice though, I contacted a seller on ebay about buying a replacement power supply. Hopefully they reply soon.

The problem is that its not rated for our mains voltage 230-240 volts , i know this as i have blown up a cheap powersupply in the same fashion you did :P

also the second hand one republican linked comes with the 230-240 volt adapter

That's the transformer, sometimes there is a small fuse that will blow instead to save it. If it smells burnt it's probably no good though.

Well, as it is only rated for 115 V there is a good chance that it either blew through the insulation in the primary coil and shorted, or the higher voltage caused a high enough current to produce enough heat to melt the primary which would also cause a short. But there could be a fuse before the transformer (is that likely though?) which might have blown, and if the insulation was good enough for the voltage (likely) then it could have blown before the heat caused a problem. However if it stinks then not likely...
