Ray Tubes SELECT and RESERVE EL34

The EL34 is a power pentode vacuum tube that was introduced by Mullard in 1955 and is usually found in an amplifierʼs final output stage. Befitting its British origins, the EL34 was commonly used in amps built by companies like Marshall and Vox—as such, it became associated with British music of that era.

Our Quality Control

Our Quality Control Each tube undergoes a seven-step quality control process, including a 24-hour burn-in period, stress tests to minimize microphonics, and critical parameters that are carefully measured to ensure consistency and accurate matching. Finally, sound engineers assess each tube under real-world listening conditions.
By the end of the quality control process, only 5% of tubes commissioned for production meet Ray Tubesʼ standards.

Our Warranty

Books have been written about the countless ways vacuum tubes can and do fail. With most manufacturers, and all New Old Stock, a tube failure leaves the user high and dry. Ray Tubes is different. All Ray Tubes products are backed by the Ray Tubes One Year Warranty, which covers manufacturing defects for twelve months from the date of purchase.
