Default Green Pre board - modular

Hi,

I am building a new preamp for my studio, so I made a new board for this pre which has pin connectors to allow for different base-boards and even different kinds of premps.

So please comment on my design, especially possible ground loops and other power-related problems.

Thanks

edit: some problems with ISP...

If you download "screenhunter" you will be able to capture the window to a jpg or a gif etc

Sure, but you still have to have EAGLE installed to capture anything...


This PCB screams trouble on top of the lungs - there is so much stray capacitance and inductance on it that you can easily turn it into wide-band transceiver.
Kubeek, search the forum and look at the works of the more experienced members - you'll learn a lot

No ! I meant he has to use screenhunter !

Screenhunter will capture his window and send it to a jpg file for our perusal !
