“Identical to the stock tube that came with my Lyr+ but somehow improved. It was not cryo or stashed, yet still really appreciably better than the stock tube.”

“Tung-Sol 6SN7GTB Platinum/No Cryo. Purchased these to replace NOS RCA Black Base of undetermined age and usage in a used Rogue Audio Model 99 Preamp. This is my first ever tube equipment I have owned. There was no difference in performance that I can tell. The new tubes still have less than 20 hours on them. Delivery was ultra fast. Ordered on a Thursday, arrived on Saturday from CA to NY. They only get four stars because I have nothing to compare them to.”

“Tung-Sol 6SN7GTB, platinum, no cryo. Bought these to replace NOS tubes of an undetermined age and hours in a used pre-amplifier I bought. I haven't noticed any drop off or improvement in performance yet. Delivery was ultra fast ordered on a Thursday afternoon (EDT) and the arrived on Saturday. Most likely they need more hours on them for a straight up comparison. Can only give them four stars as this is the first tube preamp and tubes I have ever owned. So I really have nothig to compare them to.”

“The 8 of these i have, from several sources, are all noisier than any of my NOS 6SN7's.”
