Sure... but it's not terribly blurry...
The blue scribble over the AMP in AMP CAMP 1.1 (lower left corner) is to help me keep track of the blue board vs the red board. The MOSFETs are about in their proper place on a 2Ux300mm heatsink (orig. ACA boxen used a 2U200mm heat sink) and numbered to keep track of parameters. The white block on the right is a 3D printed part that fits in the gap between the fins and will allow me to put a hole precisely in the proper place (for mounting the MOSFETs). The board will be mounted on the base-plate.

300mm x 80mm of 40mm fins is probably overkill for the ACA, but if it's worth doing... it's worth overdoing!

Please note that these were going at fire-sale prices (appropriate for Burning Amp, right?) because they were going to do another turnaround on the layout before being offered as a product, so the "official" version (v1.2 perhaps?) may look different.

Not sure about a red board (I call one the red board and the other the blue board (rather than naming them) just to keep track of parts, values and tolerances, as both are identical green circuit boards), but there appears to be more than one board layout bearing the ACA 1.1 moniker, so who knows. The photo is of the ACA 1.1 which I got at Burning Amp 2017, about a month ago.

The schematic for the ACA 1.1 (as presented at Burning Amp 2017) can be found here:
Burning Amp 2017 Updates Thread
Look at the second image in post 65, complete with the person of Nelson Pass pointing at the screen/schematic
Hope that helps.

If you were interested in ACA 2.0 (or ACA, the next generation, or whatever they decide to call it), see post 15 in this thread:
Questions about amp camp amp and linear power supply

Happy hunting/building!
