Jputb2021 - here is the picture of my Tentlabs clock : sorry not as nice as those real boards. It was working good (enough I thought) but I had later to discard the CD player (drawer stuck/not opening, that kind of thing). It has Guido's special chokes for the power supply. Dusty but not rusty. (sorry Guido if you see this)
This square clock fits for instance see the Shigaclone board
