  • 3 3/4" from bottom of base to top of glass. The MESA 5U4GB rectifier tube is our very best overall 5U4 and our tube of choice in the production of all new Mesa amps featuring this tube - Based upon classic 1950's technology, the 5U4GB is a vastly improved 5U4 design that is extremely reliable and consistent, as well as much more compact - It is basically the size of a 6L6 power tube, so please take special care to install them in the correct tube...

  • The MESA 5Y3 is a true, authentic 5Y3 NOS (New Old Stock) equivalent modeled after the original Phillips 5Y3 and is built to our exacting specification for use in our Lone Star Special - 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.

Introduced in 1970, the Boogie amp began to re-define the guitar amp. Leading players liked what they heard, and word spread. Today, Mesa/Boogie's goal is to build the best musical amplifiers they possibly can, and treat each customer as they would wish to be treated.
