[sdiy] PCB layout advice

[Anders Sponton]

Hi all!
I use to read this:

BTW
My site C.A.G. is up and running again. Some new (old) scans.

I'm working on some circuits that utilize digital functions so there are some audio frequency square waves which could cause noise but I'm trying to keep those away from amp sections.
