Post a good quality photo of the face of the driver board if no one can help. It may be similar to other amps.

What do you need to be able to see in a photo? The following photo should be similar to your board. If it is, email me. I have a diagram that should be close.

The carbonized parts of the board will have to be cut away.

The attached photo shows one way to repair these boards. The collectors are soldered to the ground plane on the back of the board. The terminals of the two 220 ohm resistors (that you can't see in the photo) are soldered to pins 9 and 10.
