VACUUM TUBE TESTERS FOR SALE



I have some vintage vacuum tube testers for sale, and are listed here on this page. Anyone who has a sizeable investment in vacuum tubes or vacuum tube hi-fi equipment owes it to themselves to have a good tube tester on hand to periodically check the tubes they are using. You can take a more active role in "tube rolling" as you can match your own pairs, and keep tabs on the tubes you are currently using and know well in advance of when replacement time is near.

Tube testers have been out of production since the late 1970s, and supplies are only fair at this time. The prices have been steadily on the rise, especially with the frenzied buying of certain vintage testers on eBay and other online auction sites. Some of these sell prices of certain brands and models are grossly inflated. Hopefully on this webpage I can present good vintage tube testers at reasonable prices, away from the frenzy of the online auctionplace.
