Description
Based upon classic 1950’s technology, the 5U4GB is a new and vastly improved 5U4 design that is extremely reliable and consistent, as well as much more compact. Approximately the size of a 6L6 power tube, it produces a flexible and resilient feel that is a bit more controlled and slightly less « saggy » than the « Coke Bottle » 5U4G. Amazing feel and exceptional overall quality. Measures 3.75″ from the bottom of base to the top of glass.
Substitute in: Dual Rectifier, Lone Star, Mark V, Road King, Roadster, Stiletto, Tremoverb & Triple Rectifier.
