Looking for a pair or single of RCA twin black plate 2A3's testing anywhere from good to near nos, but would also consider single plate, box plate, or even grey plate at their fair respective price ranges

Heavily prefer tubes previously purchased from respectable dealers with test numbers and an idea on how long they were used afterword

RCA rebrands ok too. Kenrads and sylvanias are also of interest but prefer RCAs

Let me know what you have, thanks
