Welcome to the BBS, Marc
To answer your questions directly:
You can buy (autoranging) AC adapters with a standard IEC socket (i.e. PC power cord compatible) on them from the
Empeg International store
The cost is quite reasonable. And as you are in Europe you may also find a European plug version available in the store as well.
If you find a local alternative to the 'standard' power supply , then make sure of two things.
1. Make sure that the polarity of the output matches the Empeg/Rio Car - this is clearly marked on the player itself and is Centre pinpositive.
2. Make sure that the plug that comes with the unit is the right size - do not use a bigger plug as although it will fit in the socket it will damage the 'in home'/'in car' detection mechanism. You should also read the FAQ's for the player - follow
this link - there will be more information about the right sized plug etc.
This Link has some more information about using alternative AC power supplies - please read it.
As mentioned before [recent - i.e. less than about 2-3 years old] IBM Thinkpad laptop PSUs work fine and are autoranging, although their power cord socket on the PSU itself is not a IEC socket and therefore it can be a little more difficult to obtain the right cord with the right plug that matches your present country if you travel. But a normal 'plug' convertor will work in that case.
