Asking $299 for the pair. Matched pair of NOS-Test authentic Visseaux 6V6GT power tubes in their original boxes. Visseaux 6V6s are ultra-rare due to their highly refined sonics and not many were originally made. I was amazed to find no such tubes on Ebay.
The pair I have were tested on a calibrated TV-10D/U dynamic transconductance tube tester, and both test at 4200 Gm, which is the NOS specification for this power tube (minimum is 2400). Also tested on a calibrated EICO 666 dynamic emissions tester at 120 and 120, which is what new 6V6 test at (min is 60). They will come in their original boxes. Pictures will be posted soon or on request.
I have other ultra-rare NOS-test 6V6 and will list when I have time; e.g., by Mazda and maybe Pope if I can find them.
