I _think_ what @DeepBlueMind is asking about is the power input on the Zynthian V5.1.  
It is a fairly common “barrel” connector used on many guitar pedals. I _believe_ it is 5.5x2.5mm but I’m not sure about that.

This power supply did work and fit:

and i did not need to use the adapter that came with it.
