Default Group Buy for LM4651/ 4652 Subwoofer Amplifier PCB

Is there interest in doing a group buy for a PCB for the LM4651/ 4652 Sub Woofer Amplifier chips (National Semiconductor: http://www.national.com/pf/LM/LM4651.html).

This group buy would be for the printed circuit board and possibly components depending on everyone's interest. The printed circuit board would be double sided, with solder mask and silk screen.

Cost will depend upon quantity. I'm thinking the design would be identical to National's eval board which is a proven design and gives some flexibility.

Let me know if you are interested.

Perhaps if you started a thread to discuss the advantages over using say LM4780 you could drum up some more interest?

I need a bit more than 170W though. Will your design allow us to parallel more chips for more power?

Maybe you should post something in the Class D forum? You seem to be attracting quite a few stupid posts.
I may be in depending on price.
