Sylvania 6L6 duet matched tubes in original boxes.  Bases show no wear.  Pins looks clean and unused.  Tested in our Orange tube tester as GOOD and closely matched.  Tested in an amp for microphonics and audible noise.  They sound awesome!

US made tubes last a long time, they're definitely worth the investment versus modern tubes.
