6L6EH Beter than the RCA. Modeled after the vintage RCA 6L6GC “blackplate,” the 6L6GCEH features larger plate dimensions and improved grid structure for increased power handling capabilities. Also features mica spacers with metal springs to eliminate tube ratle and miscrophonics. The 6L6GCEH offers tone and performance superior to any other 6L6 or KT66 type.
12AU7EH Finally, 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.
