The Mesa Boogie 5Y3 rectifier tube is a true, authentic 5Y3 NOS (New Old Stock) equivalent modelled after the original Phillips 5Y3 and is built to Mesa Boogie's exacting specifications for use in the Mesa Boogie Lone Star Special Amplifier. This tube produces a sultry vintage sag, creating a silky, smooth feel on the strings and provides the most sag of all of our rectifier tubes.
Mesa Boogie starts with the finest amp tubes from around the world, tests and matches each one under simulated operating conditions to the tightest, most demanding industry spec. Then backs them with the best warranty in the business.
