I have a bunch of 6SN7 tubes, and now that I have sold the amp that used them I will put them up for sale. All of the ones listed are pairs, and they have been tested on my tube tester. Many of these were very highly rated for sound quality. Let me know if you are interested in any of these and I can provide pictures or more info.
