Hi All
I played around with the LM4651/52 chip-set own my own PCB some time ago. I did make it work in the end, put it was by no means easy and the PCB was almost "dead" by all the modification.
I would now like to play around with that chip-set again since I think it has a great potential.
To start on a fresh I would like to use the NSC full-range board (at least for now).
NSC have made the Gerber-file for this board public ( see http://www.national.com/appinfo/audio/0,1819,968,00.html) and I have found a place where they can make it in a good quality.
However as you most likley already know, having one or two high quality boards made for you is rather expensive.
I would therefor ask if there are any other audio DIY-people in the world that are interestet in this PCB. ??
I would estimate that it could be made and shipped anywhere in the world for around US$15 (max. US$20), if we are enough.
I don't want to turn this into a official group-buy. Just drop me a line if you would like the board for the indicated price.
I trust you, so if we do it, I will put up the money and ask you for the money before I ship the board to you.
It should be said that I can't help you with mounting the board /making the amplifier in any way and since this a class-D amp it should NOT be your first DIY-project.
Looking forward to hear from YOU !
Have fun
Thomas
