I think I just smoked my Amp

Well I managed to locate two fuses

the first, in the obvious place next to the power cable was one of these:

Due to the opaque nature of the cylinder, I can’t see whether the filament is intact or not.

The second fuse was on the main board. It was in a really awkward spot, but I managed to get it prised loose with a long wooden skewer. It’s one of these:

It looks to be intact, but I’ve had fuses on my bike that looked good, but actually needed replaced.

I’m going to go ahead and order both, and cross my fingers.

If it was the fuses, I’m curious to know what would cause that. Could there be something wrong with the new speakers that could cause that? Or just bad luck?

I’m guessing those are the metal devices lining the sides of the case against the heat sink. If it is a failed transistor, I’m guessing that’s game over for my amp?

Thanks to everyone who took the time to respond. The status of my D400 remains unchanged. Visual inspection didn’t reveal any possibility of shorted speaker cables.

I spent most of the day driving to retrieve my CODA amplifier from storage; maybe I should store my things closer to where I actually live 😐

I’m going to figure out how to open the case, and run down those fuses.

@bigkidz I appreciate the offer, but am located in Oregon, and trying to avoid shipping this amp if at all possible (no original packing materials). Coincidentally, my speakers were shipped from NJ.

Well, nothing amiss with these speakers. My CODA amp is driving them fine. Too bad it’s such a lousy match for my pre.

Well this is interesting… in the schematic, it calls for a Bussman MDQ-8 fuse, but what I found in the amp was an MDA-8. Is this a problem?

Thanks for the offer; it’s awesome that you’ve got a tech that could work on your d240. If I need to my amp serviced, I’m hoping to be able to get that done locally. Not only would shipping an amp of this size be extremely expensive, but I don’t have the original packaging materials and wouldn’t even know where to begin in terms of trying to pack something like this for shipping.

You sir, are a gentleman and a scholar! You totally nailed it, replacing the fuse got it back up and running. Feeling a little sheepish that I didn’t figure that one out on my own.

I replaced the fuse with an mdq-8, as indicated by the schematic. Still curious about the mda-8 fuse I pulled out of the unit, wondering if that being the wrong fuse had anything to do with the failure.

Thanks to everyone that replied here; sorry for panicking and going off half-cocked when it was just a fuse.
