Power issues.

[mrgreen]

Hello there. A while ago I purchased and made the AMP6 Basic kit. Worked flawlessly, awesome amp.

However, last week i moved to uni and had major issues with it.

You see for the last year or so i have been powering it off a 12V battery. No issues.

Yesterday i tried to use it with a 12V 2A wall adaptor. As soon as contact was made on the audio input lead (whether this be skin or audio-out plug on ipod) the speakers start making a horrible loud clicking/thudding sound. I could see the cones jumping. The music could be heard behind this noise.

Unfortunately my trusty lithium battery is many miles away at home. =[

A friend of mine speculated that it might be the wall adaptor struggling to deliver enough power, might this be the case? If so, what adaptor should i buy?

Thanks. James

Some details please? and/or pics? (that adapter should power-wise work if OK)
- check if still OK with a car (-battery). no car? check with a garage nearby
- earthed adaptor? try on un-earthed wall-socket.
- locally a low voltage/or bad adaptor: so IS it about 12V or 8-9V upto 14-16V?
- anything might have come loose?

Don't try too long with this behaviour...

Also, what are you using for your audio source. This could be a ground loop issue between the PS and audion source device with the AMP6-Basic suffering in the middle of it all.
Please post a picture or specs (make & model) of the 12V 2A wall adaptor.

Cheers
