Right! In two pictures only the + and - terminals for the power supply seem to be connected. Nothing goes to the GND connection ! Unless it is soldered underneath the board.
Wow thanks for all the replies guys.
I have been busy with other things lately and haven't had time to play.
I got another transformer for this board and I have a somewhat sneaking suspicion that some of the noise was due to unrelated issues (I noticed a lot of noise in something else I was testing and realized my crummy soldering iron was plugged into the same crummy powerbar)
I'll pull out the board again sometime this week and get more information!

Apologies sereal

Yes, I am going to investigate further at some point this week. I apologize for going dark on this thread - other things got in the way.
