Mesa Boogie 5Y3 Tube
The Mesa 5Y3 is a true, authentic 5Y3 NOS (New Old Stock) equivalent modeled after the original Phillips 5Y3 and is built to their 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 Mesa's rectifier tubes.
