Royer Labs 140-NM Replacement Magnet for EMT 140 Reverb Plates
The Royer Labs 140-NM is a precision-engineered replacement magnet motor assembly designed to restore and enhance the performance of classic EMT 140 plate reverbs. Intended as a direct drop-in replacement for worn, weakened, or missing original magnet assemblies, the 140-NM delivers higher magnetic flux density, improved drive coil responsiveness, and reduced distortionbringing vintage plates back to full operating spec.
Designed by Royer Labs with deep knowledge of EMT plate behavior, the 140-NM offers a measurable and audible improvement in efficiency and clarity while preserving the musical character that made the EMT 140 a studio legend.
