One pair of vintage Tung-Sol 12AT7 tubes, tested, used.Ca. 1950s-‘60s. Silkscreening on both shows some wear but Tung-Sol made in U.S.A. and part of the code number, 2501-3 can be read. “Tung-Sol” part of the “U.S.A.” can be made out but the code number isn’t legible. Both have “12AT7 3” etched in the glass.One tube has a wire “D” getter, the other one has a round wire halo. Gray “wing” plates.The tube with the round halo tests 101/105, the other tube tests 118/118.Getter flashing looks excellent on both, very bright and chrome-like.Both tubes are tested on my B&K Dyna-Jet 606 emissions type tester, minimum good is 65, max is 120 on this machine. Zero grid emissions, no abnormal shorts. Not selling as matched since I don\'t own equipment capable of matching tubes. Not tested for microphonics since I don\'t have a tube amp available at the moment to do so.Sold as satisfaction guaranteed, returnable if no good. Buyer to pay all shipping & handling costs in the event of a return. No price adjustments.
