Yahoo has a Seeburg group. It takes a few times for the admin to allow access. Dunno why.
http://lists.netlojix.com/pipermail/jukebox-list/Google is also hosting the oa juikebox discussion board - aka old alt. groups
Not a lot of activity, but I have found answers
https://groups.google.com/forum/?hl=en&fromgroups#!forum/alt.collecting.juke-boxes
And there are several members here with jukeboxes or restore them ( oh, like me)
Ask away.
Are any of these groups as friendly and informative as this site? Not on your life.
