not having luck with Search, though i know it's in here.

i've got a meta42 with ac power in a plastic case. SDS labs style psu with +15 -15 and ground. do i do anything with the ground tab in this config? nothing?

to correct myself, the answer is right there in tangent's step-by-step.

"The META42 board is designed with single-voltage supplies in mind, and in this case, you need the TLE2426. However, you can instead use a true dual-voltage power supply, allowing you to leave out the TLE2426 and its buffer (2001G). If you do that, V+ and V- from the power supply go to the + and - pads on the board, and GND from the power supply goes to any point on the trace running around the edge of the board."
