Looking at Mouser for replacement 800ma/250V SLO-BLO 5mm x 20mm fuse, I 
see three choices (current catalog page 591): Series 215, 218, and 239.  
Which is the correct part.  And what's the difference, besides cost 
($1.23, $1.99, and $0.75 in single quantity, respectively)?

I haven't blown a fuse.  Just looking for similar parts.

Thanks,

215 = ceramic fuse body (not glass) used in high shock/vibe will work but 
overkill

218 = 'normal' fuse for Europe, what I buy

239 = 'normal' fuse for USA, what I buy

I'm trying to confirm which fuse to get for a 900 upgraded with a
HBB15-1.5A power supply.  

The unit itself seems to suggest a 1 amp verion of the 239 would work
for 110VAC.  The printed instructions, however, seem to say to use a
.5 (assuming I'm reading it right).  Both of these seem low to this
admittedly non-electronics-geek, so I thought I'd ask here, since I
know some of you have done this upgrade.

Thanks!

a) you need to use the value printed on the supply, for the proper *input 
voltage*. The 110 & 220V fuses will differ by 1/2.

b) you need to use Slo-Blo types if possible. Fuses are 5mm X 20mm (standard 
size).

c) since you are fusing the AC input side, that current will be lower than 
the output side (which is a lower *voltage*).
