This USA made 6189 12AU7 tube is an unused surplus stock, new-old-stock (NOS) preamp tube.
The 6189 / 12AU7 is a high quality preamp tube that is preferred for guitar amps and high end audio. The 6189 is a special quality tube intended for use in critical industrial and military applications in which operational dependability is of primary importance. Features of the tube include a high degree of mechanical strength and a heater-cathode construction capable of withstanding many thousand cycles. They are commonly used as phase splitter tubes. We use the 6189 in the Armadillo Tone tube boost due to its ruggedness.
