I had two working SSM 2050s from an old DIY module that never worked very well, so I build a new Aries format module based on the AR-344 design.

It was the same price to get 10 boards made, so I have 9 remaining ones. If anyone has a source of SSM 2050s and wants one or more of these boards, let me know. I can also provide the faceplate design (which is very close to the original Aries faceplate design, but I added an inverted out), and the little adapter pcbs for the alpha dual-concentric pots. It sure is hard to source good dual-concentric pots these days…
