12AU7 Tube Set - Pair

The LORE Matched 12AU7A / 6189 / 5814A Driver Tube Set consists of a carefully selected and matched pair of premium driver tubes for the LORE headphone amplifier. The 12AU7A is the standard commercial designation, while the 6189 and 5814A are premium ruggedized military-spec and industrial variants of the same tube family. Customers may select their preferred tube type, subject to availability, with every matched pair individually qualified for use in the LORE amplifier.

Each tube is supplied in a standard white tube box bearing its Röhrentest characterization data label, providing a permanent record of its measured electrical characteristics and preserving the identity of each tube throughout its service life.

The result is a matched driver tube set that preserves the exceptional transparency, channel balance, low noise, and musical realism that define the LORE listening experience.
