Louisl: I understand that the 10,000hrs refer to the duration the unit is powered on (the back switch), irrespective of whether it is playing music or not. If you read the manual carefully, it mentions somewhere that if the unit is not in use for a long time, to maximise the tube's lifetime, the unit should be powered off.
I suggest that you send an e-mail to Mr Combelles and ask him if the tube can be replaced by the user, and let us know.
