Electron Tubes

Electron Tubes — New & Used

Electron tubes (vacuum tubes, thermionic valves) are electronic components that control current flow through vacuum or gas, used in legacy amplifiers, radios, test equipment, and older instrumentation. Their robust design and unique characteristics still serve niche electronics, restoration, audio, and vintage instrumentation needs.

At Surplus Select, we offer a range of new and used OEM electron tubes, including power tubes, pre-amp tubes, specialty valves, and rare legacy models. Surplus pricing helps collectors, audio engineers, maintenance teams, and electronics hobbyists source high-quality tubes without paying premium prices.

Price Match — We match any authorized distributor on identical in-stock parts, so you can source parts at surplus pricing with distributor-level assurance.

Trade-In Credit — Have quality new surplus items? Trade them in for store credit toward the parts you actually need.

Fast U.S. Shipping — Most orders ship same or next business day from our U.S. warehouse to keep your line running.

Find Your Electron Tube Fast (Search-First)

Search by tube type or part number (e.g., 12AX7, EL34 power tube, 6V6 pre-amp tube, specialty valve NOS).
No part number? Try specs like “vacuum tube 12AX7 audio”, “EL34 power tube used”, or “vintage amplifier tube NOS”.
Need compatibility? Add tube base (octal, noval), application (audio, RF, instrumentation), or condition (new-old-stock, tested, used).
