Here’s photos of the intermediate version of the power supply in its enclosure.
The front of the unit is at the top of the image, and the back is at the bottom. You’re also looking up at the the unit in these photos. Power switch and LED indicators are at the top left of the image, all external connectors are on the panel at the bottom (see the panel arrangement). The 12V supply is above the 9V in these images. The pre-amplifier is missing in this version (there’s a pass-thru as a place holder).
You might notice the slightly odd choice of securing the components to the top of the enclosure instead of the bottom (I hope this will not prove to be a problem in terms of heat dissipation). I’ve done this because it’ll be easier to access the internals of the device due of the arrangement in the rack case. We’ll see how well this works…
