Description
The SELECT 300B captures the heart of what makes the 300B tube legendary—lush mids, graceful highs, and a coherent, musical bass foundation.
- Bass is controlled and cohesive, with moderate extension and just the right amount of body. Ideal for genres like acoustic, jazz, and classical.
- The midrange is where the SELECT 300B truly excels. Rich, full-bodied tonal character with a touch of warmth. Vocals are especially well rendered, from baritone to soprano.
- Delivers the characteristic smoothness of the 300B, with a layered treble extension and a natural sense of sparkle. A soft warmth in the upper register gives strings and female vocals a refined presence.
The 300B is a legendary tube. Introduced in 1938, it powered the cinemas of Hollywood’s Golden Age. Audiophiles have treasured it for decades for its low noise and good reliability. Ray Tubes is proud to introduce our take on a classic.
