Hi Triode Kingdom,

I've had a project on the back burner forever with similar design parameters...a pre-amp I plan to put in a rack-mount case, which is almost 19" wide, I think. Obviously plenty of room to separate the noise-makers from the noise-takers.

Btw, I recently took a class about EMI/RF interference - it was great and went a long way to explaining a lot of typical layout and wiring practices. One fundamental tenet was to, whenever possible, shield or otherwise mitigate noise sources, as opposed to noise 'victims.' I suppose one could always do both, especially if weight and cost aren't huge factors (this was an aerospace-centric class; weight is obviously critical), but often the biggest overall dB/$ payoff will be had when attacking sources.

Distance is a key strategy, since, depending on the type of noise, typical diminution is on the order of 1/(separation distance) or even 1/(separation distance)^2...you get the idea. Shielding can also yield significant benefits, as can good wiring practices.
