I always wondered if it would be possible, so I took some measurements of an MK-012 and drew up a pcb to see if everything would fit. It looks like it would. This is using one of Moby's Bv.107 transformers. I had to use MLCC caps instead of tantalums due to the lack of space, but I don't think that's a big deal. Thoughts? Would folks be interested in these boards?
