Sim Audio W-5 Fuse blew half way on the pre amp

Blowing a fuse does not sound good. Fuses are there to protect the electronics. Does it always happen when the volume is turned 1/2 way? If so something is wrong. On the other hand I have seen bad fuses although extremely rare. Also the fuse that blew was it a clear glass one which you could see it was blown? I ask because I fix computers for a living and have been doing it for 30+ years and you can sometimes tell by the way it blew how bad the problem is.

If after replacing the fuse everything is fine going past 1/2 way again I would not worry too much unless it happens again.

NO DO NOT PUT A LARGER FUSE IN!! If there is a problem you will cause excessive damage. Remember fuses are to protect the internal electronics.

Very interesting the Cary tech suggested that. It is possible the manufacturer was wrong when deciding to use a 3amp slo blow and also may have been a fairly common problem. When I did do component level troubleshooting years ago when I had an intermitten fuse blowing problem that couldn't seem to be resolved I would put in a larger fuse and the component(s) causing the problem would burn and sometimes explode. Also that was when I was a bench tech working at the manufacturer.

Paulficarella like Markwatkiss said check with the manufacturer before doing something like that. Even if out of warranty I have seen manufacturers extend warranties for some problems that they may know about but never made public.

Now I just remembered (hate getting old) my Sim dealer who wants me to replace Bryston B100 with a Sim I7. Too much $$$ for me but did say that Sim upgraded something in the I7 which they will do for free and did not make public in case used was an option for me. A good selling point promoting a company.
