..New as in new for me. Last August I bough this pieces of "furniture" for the shack, I know the post is a bit late, it's already October.
Only bough them because it was relatively inexpensive, so worst case scenario (they don't work) the box's will be used for some other project, I didn't tested yet, the decoder YR-901 looks ok, the SB-610 has some changes on the CRT tube connections so will be tested first with a bulb inline and after a small revision.
Here's some images for your viewing pleasure.

The YR-901 decoder will be a nice addition to the FT-102 Line:
...Have a nice weekend!
