Ray Tubes - SELECT EL34 Power Pentode Vacuum Tubes

Ray Tubes - SELECT EL34 Power Pentode Vacuum Tubes
The Ray Tubes SELECT EL34 is a current-production power pentode for the output stage of amplifiers designed to use EL34 tubes. It uses an eight-pin octal base and has a maximum anode dissipation rating of 25 watts. For listeners replacing a worn set or trying a different voicing, it offers a new-production option in the familiar EL34 format.
Ray Tubes hand selects and tests each tube. The gold-plated pins help resist corrosion at the socket contacts. Ray Tubes describes the EL34’s sound as having punchy, controlled bass, a warm midrange, and clear treble. That balance may appeal to listeners who want vocals to retain their body while bass lines and percussion stay distinct in dense arrangements.
We offer the SELECT EL34 in sets four. The sets accommodate amplifiers that use multiple EL34s in the output stage. Each package includes a handbook with burn-in guidance and a certificate of authenticity.
