Ray Tubes SELECT 12AT7
The 12AT7 is part of a large family of dual triodes that also includes the common 12AX7 and 12AU7 tubes.
Its higher gain and transconductance made it suitable for high frequency applications in devices like TVs and FM radios. In the world of audio, it's commonly used as a driver or phase inverter in push-pull audio circuits.

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.
