Mesa Boogie GZ34/5AR4 Rectifier Valve / Tube

MESA® 5AR4 / GZ34 RECTIFIER® TUBES

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. Used in vintage MESA amps like the Heartbreaker, Blue Angel and Maverick as well as many other vintage, non-MESA amplifiers (ie Fender Deluxe Reverb).

MESA Rectifier Tubes are premium grade and offer unsurpassed consistency and reliability for ANY tube amplifier, and certainly MESA amplifiers!

Remember… our dedication is to create the world’s finest tube amplifiers. And to achieve that goal requires a deeper commitment to tube quality… because the reputation of our amplifiers depends on it.
