(April Fools') New Product: EverTube!

We are pleased to announce the release of a brand new product: EverTube, vacuum tubes powered by our patented spring and lever system, which provides Constant Tube Tension (TM) for unprecedented tonal stability and tube life.

Constant Tube Tension (TM) not only keeps the tube running indefinitely at its ideal operating temperature, plate voltage, and bias setting, it also creates perfectly tuned overtones as the tube is driven into saturation.

With the global tube shortage threatening the very existence of tube amps everywhere, the time is right for EverTube. Don't settle for inconsistent, unreliable tubes! You need Constant Tube Tension! You need EverTube!

Available in 12AX7, EL34, 6L6, EL84, and 6V6.
(Preamp tubes $399, power tubes $799)
