Hello, I'm building a John Smith Topsy 3 and am looking for information about the "Control Board." I think this is the electronic board that accepts the MiDi signal from the source and converts it to electrical impulses for the Peterson solenoid valves in the windchest. Any ideas on educational information for installation and where to get the part will be greatly appreciated. Thanks, John Davis
