Thank you so much for the info, I will give it a try. I checked out the pictures, and it is something I can do.

Thanks for that.

A further question: Does anyone know where in the keyboard assembly the switches are, and is it possible to just blow canned air into the switch to clean it?

I've got a Kurzweil SP88, and one key, no matter how softly I touch it it plays at full volume.

Anyone have an idea what's wrong and how to fix it?

Thanks...
