All are pairs, all test well, most have been used at one point or another in my personal gear, and all are $35 per pair shipped within the US:
Telefunken 12AX7 (one labelled Fisher, the other Dynaco)
Magnavox 6BQ5 (look like Mullards)
Sylvania 6BQ5
Sovtek 2A3
RCA Command 5751 (in original boxes)GE 6072A (5 star)
I have several other vintage tubes, including a few Russian military tubes, so don't hesitate to ask if you're looking for something not listed above.
