You will probably never see another one like this. Tube tested exceptionally well on our eTracer & Hickok 800A testers. Values for plate current (mA), Rp, Gm and Mu are detailed below.

Triode #1 - Plate Current = 0.97mA \ Rp = 64974 \ Gm = 1492 \ Mu = 96.9 \ Corners = PASS Triode #2 - Plate Current = 0.96mA \ Rp = 65410 \ Gm = 1441 \ Mu = 94.2 \ Corners = PASS.

Gm Nominal = 1250 \ Minimum Good = 800. Past 30 days, we cannot offer any guarantees a vintage item will continue to function. Please keep any boxes, pins or labeling intact.

Test Results: First, we test all of our tubes, in both a calibrated tube tester, and perform a live audio test in guitar, hifi and vocal amplifiers. Our testing practices are stringent, and have given us well over a decade of satisfied clients. Still we cannot guarantee exact test result numbers or data, nor can we foresee the results you will have using our parts in your equipment. This is a widely criticized word that many electronics experts and hobbyists \ enthusiasts do not like to hear unless the item is brand new, sealed in the box. Many tube buyers only know vintage tubes by the term "NOS" and will not type "vintage" when searching for what they are looking for.

Therefore, when we list "NOS" in the title, we are only describing a vintage tube. When a tube is new in box, we will combine that with the term "NIB", or "New In Box". We will also list that the item is "NIB", "NOS", or "new in box", when a vintage item meets a certain threshold of visual quality combined with test data for it's age and type. This is normal for items stored for many decades in sometimes less than ideal climates. These items also have been understandably handled and changed hands many times over their life. This usually results in less than perfect cosmetic condition, but by no means indicates the item is used. Most audio experts are in 100% agreement on this. We hope this clears up the title term NOS for some buyers who have or will inquire about this. We are not trying to misrepresent our items, we are simply attempting to put our listings into the hands of those who want to see them. Performance Of Vintage Items: We cannot guarantee a vintage item will perform the same with or in your equipment as it did in ours, or that a vintage item will continue to function once it is used.
