Just could the fuse blowing damage the voice chips.

I had a 110v->220v power adapter. I had the Xpander on 110, and put in 
the 240v adapter in it and the 240 overloaded the 110v.

Okay.

It tunes fine.

Check out the WAV above for that answer.

Heh!

I don't want a mutant Xpander...

You (and others) please tell me how my WAV sounds.

Thanks and all the best,

Jeremy.
