    I have a Caline power brick with multiple voltages and outputs, but thought I could use one for an alternate pedalboard. I had the parts sitting around, including a suitable low-profile plastic case, so I put a power brick together yesterday. I used a 1.5A/9VAC wallwart to power it. Rectified, 9VAC turns into roughly 12.5VDC, which satisfies the requirement of 3-pin regulators for >2V more coming in than the regulated output voltage. I used 100ma regulators for 6 outputs, and 1A regulators for 2 more high-current outputs (white jacks), all conforming to the tip-ground/outside-pos standard.
    If I had different jacks, or been willing to tolerate drilling holes closer together, I probably could have provided 10 lower-current outputs, but I figured the 6+2 was enough for my needs.

    Mark, do you find the tabs on the 1A regulators enough to dissipate the heat on their own in a sealed enclosure? I usually like to mount them to a larger metal surface just to be safe but maybe I'm being overly cautious. I guess quite often a 1A source is feeding a load that really only needs have that much current/power, so there's a safety factor there.

    I was thinking about that, and your safety considerations are well-placed. I am still mulling over popping some holes into the cover. But realistically, I can't see using either of the higher-current output for anything that's much beyond 200ma.
