I've got a crate g-10 solid state combo amp. 8 inch speaker, 10-15 watt.

I've had it for almost two years and today it decided to blow a fuse. It had a 250v 1/2amp glass fuse in it. Replaced it, turned the amp on and in like 3 seconds it blew again.

Any idea what the problem could be? This is the first time I've ever even opened up an amp. I'm a do-it-yourself kinda guy so I don't wanna take it to the shop just yet. Also, I'm broke and only paid 35 bucks for it in the first place.

I was thinking it needs a bigger fuse, but that doesn't make sense, since the same size fuse worked fine until today.

Definitely not worth taking to a shop. Did you replace a slow blow fuse with a fast blow? Other than that you may need to open it up and see if there is any obvious things shorted, blown or charred.

I bought fast acting fuses. Is that bad? I don't even know if the old fuse was fast or slow.

Slo-blo allows a quick current surge without blowing. So if you need a slo-blo then that could be a problem. But the original fuse blew and that suggests you may have a another problem with the amp.

Right. Maybe the old one was just.. old? And it was slow, so the new fast one just blew because it couldn't handle it?

The circuit board looks fine. Nothing charred, no smell or anything.

That's possible. I'd get a slo-blo and maybe even up it to 3/4 amp.


Alright. I'll give it a shot. Thanks, man.

you have a short to ground.

Do not up the amp rating of the fuse, stay with 1/2 amp, find and repair the short.

Well, i have no idea how to go about finding it, let alone fixing it, so I guess I'm throwing it out.

Replace it with the correct fuse and try it before you bin it. If it was supposed to be a slow blow, put a slow blow in.

Wrap some aluminum foil around the blown fuse, turn it on and look to see what smokes. That will be your short.
