Ok.  I blew a fuse in my MnM last night.  I'm in the US so I'm using
the 115V setting.  The fuse that blew was 125mA/250V.  According to
the manual, this is the wrong fuse anyway (but two of them came with
the MnM).  So what do I want?  There are three different listings for this:
1) 250mA; no voltage listed (source = MnM beta manual)
2) 250mA/125V (source = MnM official manual)
3) 250mA/250V (source = back of the MnM itself)

I was told that the voltage doesn't matter much, just the amperage.
So will the 250mA/250V fuses I bought work alright?  And if so, which
of the above sources is wrong?

Thanks!
