I have 5 6sn7's for sale. They are all in good shape. I don't have any stats on them, but they have all been tested in audio equipment and they work well. 3 of them are sylvania's, 1 RCA, and 1 admiral. All are U.S.A. made and are NOS. I will I will let them go for $10 each. I can sell seperately, or as the group. I also have a TunSol 6sl7 which sounds great, but is a bit too much for audio equipment. Also I have an RCA UX 245 in good repair. I am asking $45 for the UX245 which from my research, seems like a reasonable price. If anyone is interested, let me know. I do have pictures of these. I can't seem to get them to post though. If anyone needs pics, let me know. As for contacting me, shoot me an email at, bernie411db@hotmail.com Thanks
