Re: [yamahacs80] Need CS80 advice for removing key spring contacts (switches...)

I'm not 100% sure what you're referring to. Here's a pic from when I had

Can you circle the part you're talking about. Better yet, take a picture 
of your keyboard, showing the problem. A picture is worth a thousand words!
