Any words of widsom changing amp fuses?

You might want to use one of those plastic fuse pullers that are popularly used with car fuses. Please be careful since your capacitors may still be charged and, even after you unplug the amp, you can still get quite a jolt if you use your fingers or meatal tools in there. The slow blows are great ideas (no comments from the peanut gallery please). Some folks have reported better sound after using ceramic fuses rather than glass ones. Some folks have also reported improved results after cleaning the fuse and fuse holder (careful there though)with contact cleaner.

Make sure you use the same type/grade fuses. If you don't you risk damaging your amp if they don't blow at the right time.

tweezers (like the ones on a Swiss Army knife) come really handy for popping them out (and plucking them, should you drop them inside the gear)

DO NOT go poking around with anything, if you touch metal tools to capacitors you will be wide awake quickly, they hold a charge for a long time after they are unplugged. I met the business end of an adcom gfa-565 power cap many years ago, sucked big time-take my word ;) Other then that it should be fairly straight forward. ~Tim

I believe Classe uses fast blow fuses. You may want to check with them before you start changing anything.
