gyraf said:+1 for a stripboard.
If you have some 12-15V AC available already, you could copy&paste the G9 phantom power part (based on a voltage tripler).
emrr said:10x less than the entire G9 at the XLR, or before the individual channel filters? And after the effects of common mode rejection on those perfectly balanced 6K8's? Let's be sure we are not apples to oranges here. I see absolutely none of the 500 rack manufacturers list PSU noise #s.
