About TubeDatabase

TubeDatabase is a personal project born out of the need to identify audio tubes.

I started collecting photos of tubes I found for sale on eBay and categorizing them by brand and design.

My hope is that this website, with its easy-to-search catalog, will help me and other tube enthusiasts identify tubes we own or discover new ones as we acquire them.

If you have insights or interesting details about the tubes cataloged here, please share your knowledge through the submission form or by getting in touch.

To add missing tubes, you can contact me directly or use the submission form.

With contributions from the community, we can preserve and share valuable knowledge about vintage tubes.

Support the archive

TubeDatabase is a free technical reference — it does not sell tubes or ads, and it costs real money to host, store media, and keep search online. If you want to help:

Donate tubes or old audio gear you no longer need — I'll photograph them for the archive (and may enjoy listening through them when they fit an amp). Prefer bits over atoms? Email me or use the submission form. Businesses that need a website and have gear or services to trade can also propose a swap.
