I continue to clean out my tube stash and today we have a nice assortment of various 6sn7 flavors. A nice pair of JAN VT-231 Tung Sol Round Plate Black Glass, a quintet of Sylvania brown base, a pair of National Union (NU) black glass, a pair of Sovteks, a pair of Chinese Golden Dragons, and a lone Westinghouse (which looks like maybe Sylvania structure inside ?).
Unfortnatelt, I do not have a tester and so cannot verify any test results. But I have used all of these and can testify that they sound good. But if, for some reason, any give you trouble, I will of course offer refund.
$395 shipping and PP included.
Feel free to ask any questions or submit any offers and I'll do my best...
