amp repair

[lithium 358]

got a kenwood kac 9013d amp here that went into protection one day in my brother's car.

it was temporarily mounted to the sub box at the time and powering a kicker l7 15 (which is now dead due to cracked magnet and shifted motor)in a ~4 cube ported box.

so what happens is every time it is powered on it will go into protection. i looked the board over and i dont see anything burnt. however i did find a capacitor with one of it's leads broken off.

here is what info i can get from the capacitor:

50v 47uF (microfarad), appears to under a brand ELNA, CE85(degree symbol)C which i assume means ceramic and 85C is max temp rating, right under that last line it reads 0718 which i assume is some type of product code, finally under that im seeing the letter "S" inside a circle-ish circle ( (S) <--has a flat bottom but round top)

thats all the info i got right now, i tried to solder it back on but the lead is just too short.

thanks for any help

Do you just need a replacement? This should work for a test cap, it is a piece of crap but I'd bet the one that was in there is as well.

That sounds like a easy fix. Just buy a new 47uf cap and solder it into the same place.

If it was indeed ELNA it should be at least half decent. That one can be used to test if only the cap is at fault.

I wouldn't drop $12 to find out though...actually I probably would. Time/money not doing it twice may be worth spending an extra $10

thanks for the hel. maybe i can ask my electronics professor if i can barrow a 47uF cap to test it out, then buy a real replacement if that fixes the problem.

Maybe post some pics here so a few guys can have a look

found a pic online

very bottom right hand side, you see the long heat sink and to the right of that u see two caps next to each other, below that is a 3rd cap, that is the one that broke off.
