Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I presume you are asking about a Seeburg jukebox, model C100.
The selector arm may have a problem, if the selector arm is what is making the chattering noise. Look into the jukebox while the problem is occurring, to see if the selector arm is reciprocating (moving back and forth rapidly), and also to generally see where the moving parts are at the time of the chattering noise.
Let me know how old, and how well-maintained or well-restored and recently (or not!...) maintained your Seeburg is, also. And I will advise you further. Thanks.
OK. Let me know, at your convenience. Thanks.
That's fine. There is no hurry about getting back to me on this, though I would like to help with it eventually. Respond at your convenience. Thanks.
This weekend is fine, Dave. Take your time.
