Up for sale is a matched pair (2 pieces) of premium vintage Siemens E82CC / 12AU7 dual triode vacuum tubes, brand new in protective white boxes. Made in Germany, these industrial high-reliability E82CC variants feature robust grey plates, crisp white logo stenciling, and top ring getters. Highly prized in the audiophile community for their remarkable transparency, extended high-frequency detail, tight bass resolution, and exceptionally quiet noise floor in high-end preamplifiers and headphone amplifiers.
