I have 8 'N7s that came in a pair of freshened Atma-Sphere M-60s, this summer. They have maybe a hundred hours on them. All test strong and with tight...say, within 10% and usually closer...matching between sections. Since my B&K 707 tester has not been calibrated, I won't quote the actual values, but all are way past the bottom of the 'OK' range. These 8 appear to be the same as these...
http://www.tubedepot.com/si-6sn7gt.html ...but for the 'G Electron Tube' text. $15 each there; for mine, only $8 each or $15 per pair or $29 per quad or $56 for all 8, all plus $5 Priority Mail. PayPal, personal checks and CCs/MOs happily accepted.
E-mail me directly at jeffreybehr(at)cox(dot)net for more-prompt reply.
