Ray Tubes Launches Select 5U4 Rectifier Tubes

Ray Tubes added another tube model to its Ray Tubes Select Collection. The Oakland-based vacuum tube company expanded its line-up with new-production 5U4 rectifier tubes in its Select Collection Rectifiers. Although the 5U4 aren't always top-of-mind, they’re a crucial component of tube amps for high-end audio, besides being an essential component in guitar amplifiers, prized for its ability to handle high peak currents. Select 5U4 vacuum tubes are now available from Ray Tubes' global network of retail partners.

Ray Tubes announced new-production 12AU7 tubes in both its Core and Select Collections. With this addition, Ray Tubes is now supplying the most common vacuum tubes, including the 12AU7, 12AX7, EL34, 6SN7, KT88, and 300B, all available through its network of retail and brand partners. All products from Ray Tubes are designed and tested specifically for audio applications and come with a one-year warranty, which is a great assurance compared to the risks of buying New-Old-Stock items.
