(still available as of 10/15/12) I bought these as NOS tubes a few months back. They weren't used very often over that time and are still virtually new. One of the best 6SN7s out there, you can't beat it at this price. These tubes arguably produce the most beautiful midrange and top end in this family of tubes. Its midrange is clear and open, and the treble is smooth as butter yet unrivaled in its detail and spatial separation. Zero listener fatigue.
