MESA/Boogie 5Y3 Rectifier Tube

The Mesa/Boogie 5Y3 rectifier tube is a true, authentic 5Y3 NOS (New Old Stock) equivalent modeled after the original Phillips 5Y3 and built to Mesa/Boogie's exacting specifications for use in the Mesa/Boogie Lone Star Special amplifier. This tube produces a sultry vintage sag to create a silky, smooth feel on the string.
