Bombadil, seems to be circuit dependent, eh? I remember my DH Inspire Hot Rod came with a brand new TS 6SN7, sounded okay I'd say, and okay in my current preamp, just a different presentation, more forward, a tad harsh at times and I really have to run the preamp warm for 3+ hours. Not sure how they may sound after 100hrs burn in.
By chance was this your post on AK about $78,000 VAC amps using new Tung Sol 6SN7s?
