Hohner Clavinet key springs:
These hohner clavinet key springs are available to bring back the quick responce to your keys. Old Clavinet key springs loose their tension over time, some people actually pull the spring and hook it a few rings down to pull the spring tension tighter. This is one way to rig it, but a new set of springs is much better. If your clavinet keys sag or do not return as fast or the feeling is just weak, it may be time to replace your springs and restore the original clavinet feel.
