Ray Tubes SELECT 2A3

SELECT 2A3 The 2A3 was introduced by RCA in the 1930s for use in large radios, public address systems, and early hi-fi setups. Despite its notoriously complex filament, the 2A3 saw widespread use in military applications and in the post-war hi-fi boom. It was also a favorite of Paul Klipsch, who in 1946 invented his namesake Klipschorn loudspeaker. Product Highlights SELECT is the Ray Tubes tier most listeners should start with.

Designed and manufactured by a team with decades of experience Hand-selected by engineers to ensure only the top tubes make the cut Gold pins for durability and longevity Substantially more consistent performance than New Old Stock Unlike NOS and most other new production, covered by the Ray Tubes One Year Warranty Sounds Characteristics  The SELECT 2A3 takes the iconic 2A3 and adds the refinement and tonal balance that define SELECT. Whether in low-power amps or high-fidelity systems, the SELECT 2A3 brings resolution and a natural, unforced tone to acoustic and vocal recordings. The bass extension is moderate but well-controlled. Kick drums, double bass, and cellos sound clean and coherent. The midrange frequencies offer gently warm tonality, with an outstanding sense of resolution. Voices and instruments emerge naturally from the soundstage with a sense of air and dimensionality. The treble performance offers excellent extension without excessive coloration. Details are precise yet never fatiguing.
