What's in the Box?
The Special Limited Edition 5U4 Anniversary Edition takes an already exceptional rectifier and gives it an even more exclusive presentation. Created for enthusiasts who want something beyond the standard Anniversary Edition, this version combines the character of our premium 5U4 with a distinctive limited-edition look. For the standard Anniversary Edition, it is a statement piece for the serious tube enthusiast who values performance, craftsmanship, and exclusivity.
The 5U4 is a directly heated full-wave rectifier tube intended for high-voltage power-supply rectification in vacuum-tube equipment, making it an essential part of an amplifier's power supply. This Special Limited Edition retains the fundamental 5U4 rectifier format while adding the distinctive presentation that separates it from the standard Anniversary Edition. It is an excellent choice for a premium amplifier where the appearance and selection of every tube matter just as much as the components inside the chassis.
