Description:

The MESA 5AR4 rectifier tube produces a vintage feel with light to mild "sag" - While it produces more "sag" than Silicon Diodes, it is the least "saggy" of our tube rectifier offerings (The Rectifier is part of the Power Supply and its purpose is to convert AC into DC)

Mesa Boogie starts with only the finest tubes available from around the world. They then test and match every tube, while under the stress of actual operating conditions, to the tightest, most demanding specifications in the industry with the use of the Mesa Boogie proprietary, aerospace designed tube analysis system called Robotube™. They accept only the "finest of the finest" and back them with the best warranty in the business for a minimum of six months.
