Looking for NAD C275BEE Left Channel

No board help, but you might find the attached thread interesting (looks to be a design flaw).

Wow, that's pretty interesting, and the heat may be related. It was on start up that it happened. Within a few seconds smoke was billowing out of the top. The board was quite charred. 

PS:

Check this guy out who mentions an extra board.

Nice find! I had previously looked on eBay and didn't see this one. Interesting that he got boards from NAD. I was told they didn't have them anymore.
