Survey of interest in PCBs of Mauro's designs

I have ordered a dozen pieces each of two of Mauro Penasa's designs:

1) The non-inverting GC with inverting power stage using LM3886.

2) Mauro's reference GC design.

I will be recieving them in a couple of weeks.

I already have several of these spoken for but I would like to know if there is any interest in a group buy. I would be willing with Mauro's permission to sell these boards inexpensively to anyone who wants them as Mauro has indicated that we are free to use the design. Full credit will be given to Mauro for his fine work.

Thank You,
Russ
