Hi Crawford,
Yes it's true. there has to be done only a slight modification to let the Beolabs 2500 work with 240 Volts.
You can find it here.
But keep in mind that the audio has also to be converted to 240V mains.
For all the informations here at beoworld you should consider an upgrade of your memebership. This wold give you access to all service manuals available here.
