Hi guys,
sorry, it took a while to add the information, but the Version 2 of the DCX76 is now online: https://www.1001-digital.de/pages/digitaltechnik/lokdecoder/ct-elektronik-tran/tran-dcx76.php
I have also checked the pads for GND, the one that is marked on the red circuit board is still connected to the GND pad on the green one, so you may use both of them if you wish. Note that Tran forgot to uncover the pads for AUX1 and AUX2 on version 2, so you have to use the 2 pads on the upper side of the decoder. Unfortunately they are harder to connect, there are some chips nearby.
Best regards
Carsten
