Elektron Musical Instruments

hi. i need to get a new power cable for machinedrum. the one i have got 
bent funny and isn't werking now. should i just go to an electronics 
store and try and get a compatable cable? can i order a new one from 
elektron? 

i also had a horrible thing happen(poor md). i had md on my lap and 
knocked off the level knob(it hit another keyboard i have). the level 
still werks but it took the post the knob sits on and the knob itself 
off. what would be the best way to fix this? i have several friends who 
do electronic repairs. at first we thought the entire petionometer 
should be repalced now we're thinking superglue? i had emailed elektron 
in the past about this and never receieved a reply. i bought md from 
elektron themselves not a retailer. i love md and want to tweak it and 
use it for a show on may 20 but with no power cable am unable. 

thank you in advance.
