Thanks Robiwon for sending me the sound board. As of today (Saturday) I have not yet received it.
The second Obi-Wan saber I got from Fry's (it was an exchange for the first one that had a bad blade) malfunctioned! The first day I had it the sound started to fail. The volume would intermittently drop to a low level and was full of static. One time the blade lit up but there was no sound. As I prepared to return it, I fired it up one last time and the bottom part of the blade near the hilt would not light up! So I returned it and got a third one. Third times a charm? I hope so.
