Mesa/Boogie 5Y3 Individual Rec Tube

The MESA 5Y3 is a true, authentic 5Y3 NOS (New Old Stock) equivalent modeled after the original Phillips 5Y3 and is built to Mesa's exacting specification for use in their 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 their rectifier tubes.
