I just did the SGM sound fix this morning.  I have very little experience with a soldering iron but found it took longer to take the Adam apart than to fix it. It is a very easy fix and I am so glad I did it.   TBH I think this fix can be done without soldering if you just extend the green wire a bit and attach a very small aligator clip. Then just attach the clip[ to the cap.       I ran out of hot glue so I just used some electrical tape to hold the wire
