tholt- be VERY careful buying tubes on "flea-bay". If you don't have ready access to a tester and a return guarantee, I would avoid it. I would estimate that 50% of the NOS tubes i bought there (before I had a tester) barely make minimum good and more than 25% did not even test that high. So maybe a 1 in 4 chance of getting a tube that is even close to NOS. And then there is the counterfeit problem. I'm sure there are exceptions, and YMMV. As for me, I'm sticking to tube sellers on on 'Gon as well as the better known internet sellers like Vintage Tube Services and Upscale Audio.
