1 used but new testing Genalex KT66 grey glass power tube. Test at 104%.  Strong life testing, no shorts or grid emissions indicated on a B&K 747b mutual conductance tester. Any reading above 55% is considered passing and NOS usually tests between 100-120% . If no box is shown they will ship in a vintage box from another manufacturer. Satisfaction guaranteed.  Any issues please contact me directly for a solution.   Some sellers love telling you about their great testers and the wizards who conduct black magic to get them into a enlightened state. Even the best tester is only a tool.  The real test is in the circuit.  The B&K I use has been refurbished and works great.  That is why I  give a 30 day return period.  If the tube does not meet your expectations I will refund the purchase price and shipping.   Regarding shipping,  the most a first class tube package will cost to ship using the ebay shipping label service is $3.40.  If shipping charges are over $4 for a single, 13oz and below tube, you are being overcharged. Free shipping on additional tubes purchased at the same time. Wait for a invoice or I can refund the difference. Thanks for looking!
