100% Guaranteed Tubes All tubes are tested for Gm, shorts, leaks, gas and noise on one of our calibrated HickokTV-7 D/U tube testers. Buy from the experts and avoid hassle! Visit our store to view our inventory of thousands of tubes. We are an authorized dealer for New Sensor products including Sovtek, Electro-Harmonix, Mullard, Tung-Sol and Genalex. We sell A grade quality stock, not factory seconds like many other sellers. You may notice other sellers listings these at a lower price. New Sensor increased the price on all of their tubes this year. Anyone selling their tubes below market value is selling old stock that will run out at that price or B-stock. These are fresh tubes. WARRANTIED FOR 90 DAYS! Brand New Plate Current Matched Sextet (6) Tung-Sol Reissue 5881 Vacuum Tubes Please note, the 5881 and 6L6WC are the same tube. The 5881 is rated for just 400 volts on the plate and therefore is NOT a suitable replacement for the 6L6GC. We will only warranty your tubes if you are using them in an amplifier that calls for the 5881 or 6L6WC specifically. They really got it right with this one, to my ears, it's hard to hear a difference between these and the originals. You have very little choice with the 5881 as almost all of the vintage ones were made by Tung-Sol. It may be worth having a set of both to compare yourself! Testing and Matching Double-tested and/or matched by Gm, Plate Current, Shorts, Leaks, Gas at real world voltages on a Maxi-Matcher tube tester. Guaranteed to test at or above new / nos values.
