    Here is an image of what the FM-3 motherboard would look like. You'll notice that all 7-pin sockets in place,I made a mistake when I was editing the 9-pin,it changed all of them. You'll notice the DIP switches in place.

    Hi Denny,

    The mock up photo of your FM-3 board looks really good. When you get your first actual board made up post a photo of it on this thread. Having a single board like that with a single ground plane is much better idea than Dynaco's three separate boards.

    Bob,

    Will do,
    and yes a single ground will work really well, cleaning up some of the residual noise and help
    Some on the RF side. Thanks again
