Hey Everyone,

The 7-channel factory BOSE amplifier in my Dad's 1993 Merecedes S-Class stoped working (popping and cracking noises). This is a common problem with this amplifier, and it needs to be "rebuilt".

The rebuilding involves removing and replacing each of the 78 capacitors in the amplifier. I have already bought the new capacitors off of DigiKey and was going to fix the amp myself, but decided not to as I am not an experienced sauterer. I have a chart detailing which capacitor # goes where on the board, so there is nothing to really figure out.

Does anyone here rebuild amps? Or does anyone have a good contact? Basically, I need someone who is a good sauterer. Everything is already figured out, and the part are already here. Is there someone here who could help me out? I would REALLY appreciate it!!

Thanks!
Bryan

Wow

I've fixed a few amps myself by replacing a few caps, resistors ans MOSFETS, but 78! [img]graemlins/jawdrop.gif[/img] That's a tonne of tedious work! All the best in getting that thing fixed.

It's going to cost you more to get it fixed than buy a new aftermarket amp and get it installed.

ususally bose uses a nonconvential input level and the factory deck dosn't usually have enough output to drive a aftermarket amp properly

Replacing 78 capacitors is crazy.....

A half decent tech will be able to find the leaky cap(s) or bad solder joints.

There are lots of car audio repair places down here in burlington, but you might want to scan ebay for a used or scrap amp, the end result may be less expensive and more reliable - having to change that many caps scares me.
