Any words of widsom changing amp fuses?

Just got a Classe 301 and believe when I pushed it back in my cabinet two speaker wires touched together, I saw a spark and the amp went dead. Trying to see if its just the outside fuse, if not I have to pop the top. Called Classe , they were very helpful and friendly. Anyway if I have to open it up any words of wisdom? Did a search on this forum and I can see Im not the only one who's ever made this dumb mistake. Thanks.

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.

Sorry about that suggestion to go with slow blows without adding any caveats. Please do check with the manufacturer before going that route if the amp uses fast blows now -- but it could save some future hassle if it is OK to use slow blows. While you are checking, also ask if ceramic fuses of the same type (amperage, blow speed, size) would be OK. They might improve the sound.
