Hey Mike,

Do you still have this amp? I'm looking for the values of these capacitors. i know one is a 10uF, and another is a 6.8uF.

The board designations are C514, C515, and C516.

Here is a pic of the amp/area I'm working on.

Thanks!

Hey mRgSr. I have this amp posted i nthe other thread here:

JL Audio 1000/1

However... The owner said for ~years the amp was screwed to the back of a dual 12" subwoofer speaker box. I'm guessing rattles and distortion because the gains were at 100% when i got it.

See attached.

When working on the JL amps, I tape the boards to the top of the capacitors (the LEDs drop between the caps). This keeps them out of the way and prevents them from shorting out to the main board when working on the amp. If you look closely, you can also see that Goop has been applied to the wires to prevent stressing the wires at the point where the insulation stops. This prevents them from breaking.

Just took out the diodes and caps i just put in and took all of the power supply fets out. Its still showing a direct short between power and ground terminals (0.2 ohms).


Any idea what to check?
