The Yamaha AN1x Synthesizer mailing list

Its been a couple of years since I started this post. I think I know what the culprit of this problem with the sounds on my AN1x were. The culprit was the power supply. 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 again.

I am convinced that the power supply I used originally on my AN1x and the new one I bought from Maplin was and is the problem.
