I would like to help, but it is unclera to me what actually happened that blew your fuse ;-)
You used as different power cord? Where did you plug it in? at 230V mains or at 110V mains? Where do you find 230V and 110V mains in the same home installation?
The switching power supply of the XPander has, due to its nature, protection against surge and overvoltage, i.e. setting to 110V and plugging in 230V.
The primary (mains) side of the PSR does not let more current in as needed no overvoltage should occur on the secondary side. Besides, the voltage supply for the voice chips have additional linear voltage regulators, that assure +/12 Volt output even if the input is three time as much.
The only thing that would suffer from overvoltage is the transformer, because approx. twice the current would flow at twice the voltage. That's why the fuse blew.
On the other hand, there might be a problem to the PSR itself that blew the fuse, which is not in direct relation to the "change of the power cord", in particular if you never applied overvoltage. But you reported that now the XPander is operating normal and even is performing the tuning routines.
As regards the voices, when using ROTATE assignment (standard), does each voice sound the same? Use different filter settings and different wave form settings. IF in all instances all voice sound the same, I seriously doubt that there is damage to the voices. Damage is something unpredictable. Else, we will have to claim that there is a stable condition 1 for all voices which existed before the fuse blew, and a second stable condition 2, after the event. This is very unlikely. If yes, you have created an all new version of Oberheim Voices and you should sell your XPander to a collector of rarities ;-)
