Elektron Musical Instruments

Hi, 
  I've got a bit of a problem. I guess a chip in my Sidstation is 
dead. Elektron offered to send me a new one(chip), and install it 
myself. I was just wondering if anyone has had any experience 
installing these, and could tell me if it's a difficult job. If it 
is, should I just send it back to elektron for servicing? Any advice, 
or tips would be greatly appreciated. 


                                 Thanks,
                                 Isaiah
