I have nine OA2 tubes on hand. These are 7-pin gas voltage regulators. I measured 7 of them and they were all good on the calibrated TV-7/U I was borrowing, but I found the other two tubes in my pile after I had to give back the tester so they are untested (but likely good considering all the others measured well).

The good ones measured 80, 84, 68, 64, 82, 76, and 93 for gas (minimum good on this tester is 40). Most are probably RCA, from what I can tell, but one is a British Amperex (the 80).

Asking $20 shipped OBO.
