Up for sale is a closely matched quad (4 pieces) of premium vintage Siemens E82CC / 12AU7 dual triode 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.
