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.

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.
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.
