Problem with my Atma-Sphere M60

Well, not knowing which model your amp is, I will refer you to this Atma-Sphere webpage with all of the manuals. Fuse details are within:

Not sure a Best Buy would have it (and not sure I want to be anywhere near a Best Buy on Christmas Eve). But I'd guess Radio Shack or a hardware store would have the fuse you need.

If you have a radio shack near by , they should be able to help you out on getting the correct fuse.

5A should be Fast blow.

Check MusicDirect.com as they have a good list of fuses from HiFi Tunning to match your needs.

NO NO NO. Lapierre is INCORRECT.

My apologies for shouting Lapierre but I didn't want someone to make a mistake on incorrect advice. Look at each of the manuals for the M-60s at the link I provided. For each model, the fuse is always SLOW.

Not sure where Lapierre got this idea, But it is completely INCORRECT.

I've also asked Atma-Sphere folks about the boutique fuses from HiFi Tuning. They don't think pricey fuses make an improvement in the sound in their designs.

Lapierre's post is a great example of why posting questions like the OPs is a bad idea on Audiogon or an audio forum when it is possible to call/e-mail the manufacturer or find the documentation with the info you need on a manufacturer's website.

OK, rant over. Happy holidays everyone. Hope you can all enjoy some sonic bliss in the New Year.

I posted a longer rant about the inadvisability of asking questions like this. But it hasn't posted for some reason. Short version:

Lapierre is incorrect. For all models of M-60 the fuses are slow blow fuses, as the manuals I linked to make perfectly clear.

For questions like this, call/e-mail the manufacturer/retailer or go the manufacturer's webpage. Not a good thing to ask in a forum due to potentially disastrous incorrect information that might be given.

Thanks guys, I've already checked the owners manual. I have the latest version of the M60. The manual is not clear. It says I need a 0.5 amp fuse but when I took it to radioshack it was clear the fuse is 3 amp. The 0.5 amp fuse wire is very thin but the one that blew has thicker wire just like the 3 amp fuse. I've contacted atmasphere but no replies yet.

Roscoeii, don't worry. I know they're slow blow fuses. I figured out I need 3 amp fuse, not the 0.5 amp. I just looked at the fuses in the other working mono block to confirm which fuse I need. There are no 5 amp fuses on the M60.

I just looked at the fuses in the other working mono block to confirm which fuse I need.

There you go, one problem solved. The bigger problem I see is,why did the fuse blow on a six month old amp.

My bag Dracule. I figured you would just look at the other fuses to determine what you needed.

HiFi Tuning manufactures fuses SLOW and FAST. At first glance I only saw FAST 5A fuse which is what I posted.

Hopefully you get better fuses.

Thanks for your responses. Lapierre, Ralph told me it was most likely tube arcing that blew the fuse. Now, I have to check all the tubes in that mono block. Not fun.

It takes about 30 seconds to check for a tube that is arcing. Just knock on the top of the tube. That's the time-honored tradition since there have been power tubes.
