Burnt XS6600....should I just cut my losses?

ProperID · Post by **ProperID** » Wed May 06, 2009 6:07 am

I picked up this XS6600 for dirt cheap hoping to put it in my girlfriend's car...but I take a sec to look over the internals before I go about installing it (not that I know much of anything about what I'm looking at, but I wanted to make sure it at least looked okay) and it looks like it has been on fire. From what I see (and I'm guessing here), it looks like maybe half of the 4 channel section has burned up, so I'm thinking maybe I can just use the other 2 channels and the sub channel and be done with it (I doubt it's easily repairable).

Any thoughts? Should I even try hooking it up? If I decide to use it, what should I do to stop that section from getting power (I don't want it to catch on fire again). Can I just leave 1 of the fuses out?

Ugh...you get what you pay for.

You can see higher detailed pics in this Picasa gallery....just ignore the pics of the airbox and bent speaker terminal.

As I expected...good thing it was cheap.

WAIT!!!

Maybe it can be saved.

Take some detailed photos of the damage and post them.

Ok, I'm dumb. I looked at the link to the better photos. I think it can be fixed, but it would be a lot of work.

Just as a guess....what all do you think would be involved in saving this?

I don't mind putting in the work (I don't want to just throw it away!), but I also don't know if I have the skills that would be necessary. I can solder, but I generally feel only slightly adequate at it. It looks like the parts on the fried section of the amp are duplicated at the top, so at least I will have a visual guide if I decide to try to repair it.

Also....any idea what would have caused this?

I would start by cleaning it the best you can first to see what is going on. I would use lacquer thinner (cuts through the black soot fast) and a small brush or even a toothbrush. Pull the board from the amp and start cleaning it up.

Once you clean it you can see what is bad and what is not.

My guess is the channel was loaded down pretty heavy and the connections at those resistors started arcing bad which lit it up. Just a guess though.

I'll be pretty busy tonight, but maybe I can clean it up tomorrow. Thanks.

Im pretty sure a little bit of duct tape could fix that right up

Seriously though. Sorry to hear ya didnt get the deal you thought ya did.

That can be fixed but it'd be a project and a half. It would most likely involve epoxy and thru-hole repair. If you clean that up with iso the damage will be easier to see. By the time you figured out what shorted to make it that hot (assuming it wasn't the cap), and replaced all the toasted components you'd be much better at soldering

Nothing to lose right? You have a good side to compare components from at least.
