The voltage and current specifications on that adapter were perfect. What you probably didn't check is if it was AC or DC, and if DC what polarity the connector was.

When you contact support David can arrange to bring your player to the UK and repair it. You may have just blown a diode or solid state fuse, but it sounds like you could have also burned a track off the board. There isn't usually a problem fixing such issues. David can also advise you on selecting (and testing) a suitable adapter.
