Try the new Tung-Sol 6SN7 re-issues from Russia. You can get them at any of the big tube-sellers like Tube Depot. I have had then in my Supratek for about 40 hours of on-time so far and I LOVE them. In my system, they have most of the dynamics and slam of the Electroharmonix tubes, but with a much smoother and more accurate treble. By far the best new issue 6SN7s in my opinion.
