Make Your Good Amp Great

The SELECT Collection boosts your amp noticeably. These tubes bring out better sound, even in beginner models. Each tube is handpicked by our engineers for clarity, texture, and detail. Your music will sound more real, emotional, and precise.

The SELECT Vacuum Tube Difference

The SELECT tubes come from the same batches as our CORE Collection. They stand out for one reason: expert judgment. Our engineers evaluate each tube for sound profile, dynamics, microphonics, gain, conductance, noise, and overall performance. This careful selection ensures only the best tubes make it into the SELECT Collection.

12-Month Warranty

We trust our product. We offer a 12-month warranty on our vacuum tubes. This warranty covers any manufacturing defects.
