Fried my amp. Need a photo of a good board

I have a L7/HK amplifier part 9261703.

I plugged in the MOST cable for the CD Changer instead of the MOST cable for the Amp, which has a +12v and GND on pins 1+2 of the pinned portion of the most connector.

So, GND went straight to a 12v feed inside the amp.

A diode caught on fire in the process. I *think* it might be the only casualty, so I'd like to replace that diode.

But... it isn't like Harman/Becker releases schematics of these boards.

Does anyone have one of these on a bench/shelf and wouldn't mind taking a picture of the board with the cover off?

Thanks!!!
