We sell vacuum tubes

We sell New In Box (NIB), fully-tested New Old Stock (NOS), used vacuum tubes, and our other products to customers globally. Shop securely here on our website, and also visit our eBay store to see our selection of additional vacuum tubes, electronics accessories, Photofact technical documents, and vinyl records.

We welcome worldwide orders here & on eBay

We also test vacuum tubes at no charge (a reasonable number of tubes, less than 15). If testing is needed to sell tubes, we charge our hourly rate, prorated for the amount of time testing takes. Pull your tubes from your equipment (make a map and mark the tubes so you can put them back in correctly) and bring them in. We generally need about 24 hours to test them.
