Hello everyone. I came a cross a beautiful MD MKii with two broken audio jacks. I created a support ticket on Elektron’s site but no answer just yet. I would ultimately want to replace every jack while I’m at it, and have not had any luck tracking down the actual part numbers to these or where to actually get them from here in the US. The ultimate thing would be purchasing an audio IO card for the machine; which I can install myself. Any info helps. Thanks everyone! 
Do you have any photos of the jacks?
I will once I head back home tonight, thanks for the help! 
I’m in the same boat, I need to replace three 1/4" jacks on my Machinedrum MK1. Haven’t heard back from Elektron yet but it’s only been a couple of days.
