Underlever Damper System
The NEW Baldassin "3-in-1" Underlever System by Renner USA maintains the design of the original Renner USA Universal Underlever System, with the flexibility of adding capstans, either in the underlever or the tray, if desired.
• Early Steinway back actions that have been damaged or worn out.
• Early back actions that require the conversion of plain-wood socket set screws to metal bushed socket screws.
• Conversions of early underlever sets having a veneer sostenuto pick-up tab to a new spring activated pick-up tab.
• Conversions of the later Teflon type back actions with the short-arm underlever.
• Early bushed type short-arm underlevers that react poorly with the geometry required for back actions.
