Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
What sort of instrument is it that is having this problem? it sound vaguely as if it might be a Baldwin or old Hammond or Leslie with a spinning tone generator, but I am not at all sure at this point.
OK. Are you into old / classic organ repair?
If not, it would be advisable to get advice, or help in person, from a professional organ repairer or restorer, in your region. What is your region please? by zip code, or by town/city and state.
(I regret that I am not able to offer Live Phone Call service at this time; However, your request is still open to other Experts in this category, and one of them may pick up on it at any time.)
You can resume this case at almost any time (in the next day or three) at
