I'm making a note of all that, and I'll probably order and try a few things when I buy the parts for my next project (should be an ez1290 - which is well documented).
I'll also read more about PSU as I understand they should always be more or less similar, and might start by just the JLM PSU kit, but that will be another thread).
I won't touch the green too much until I get stuff like proper solder lugs, shielded cable (even though it's not really necessary, I'll eventually have to get some as the ez1290 asks for some). And then maybe I'll take a closer look at getting +48, after all there's no many parts on this part of the circuit, and other voltages are fine... Well all that is done, I guess I'll addess what noise may be left.
Thanks again to everyone, expect to see me around here when I attempt the 1290...
