EH qualityFinally, a premium quality 12AU7 built to match the performance of the military-industrial original GE 6189. Low microphonics and excellent linearity offer a musical and harmonic soundstage, making the 12AU7EH tube equal to the original and a cut above the competition.
Equipped with a 12AY7 EH tube and a 12AU7 EH driver, it gives microphones the widest dynamic swing with the warmest possible tone and accuracy. It uses an actual 200-volt supply instead of the "faked out" 12 or 48 volts you’d get with common models...
Super quality 12AU7 made by the French subsidiary of Philips/Mullard. These tubes have long plates, a halo getter, and 1958 date codes. Excellent performance in both hi-fi and musical instrument applications.
