This listing is for one tube. Check it out I have more you can choose on the listing if you need more. Once these are gone that is all I have. Thanks for looking. This vintage NEC 12AD7 tube was used in many Roberts Akai Sony reel to reel tape recorder players. I pull apart these machines then test the tubes and only offer the ones that test very strong on both sides. This tube can be substituted for a 12AX7 in these vintage reel to reel recorders made back in the early 1960's This tube was designed as a low noise preamp tube that could have the filaments run on AC and not pick up hum.
