Thanks for the info.

I'm guessing the one you bought from Maplin, doesn't really perform as 
specified.

Just a few days ago I resurrected my AN1x from the attic but lost the power supply. I then found a power supply which was 12v 600mA from a hard drive I have and it worked like a charm on my AN1x with no problems with sounds going weird or fading etc. The only problem was that I had to change the internal battery. However I was a bit worried using the power supply as it is 600mA instead of the required 700mA so I went to my local Maplin store and bought a power supply with volts selector. I then adjusted the volts selector to 12V (which according to the box has 1.4amp) and connected it to my AN1x. After a while of it being connected I started having the problems with the sounds going all weird again. I then disconnected the power supply and reconnected my other power supply and it was back working normal agai
