I was reading an account of someone who swapped out the stock fuse in a Metrum Octave for an AMR fuse that reported very positive results from the move. I'm not a huge fuse guy, but for $18 I'll take the risk and experiment.
I assume the power supply case would need to be popped open to see what fuse is needed, but does anyone know the value off hand so I can get them ordered and save the hassle till it comes?
