I replace all my horn springs with genuine Yamaha springs from TOPE.

Lightened the load
These springs were installed in my Tuba Exchange/Miraphone clone tuba to lighten finger pressure needed. They worked as hoped and have reduced the finger strength needed for rapidly depressing the keys. It's a change I'm glad I made.
