RCA 6FQ7 6CG7. Black Plates. Vintage vacuum tube

Description

RCA 6FQ7 6CG7. Vintage vacuum tubes.
"These are interesting tubes and are electrically equivalent to the famous 6SN7, they just squeezed the tube down to fit in a small bottle.
These tubes do have the same pinout as the 6DJ8/6922/7308/6AQ8/6BQ7/6N1P and MAY work as substitutes in some amplifiers."
I am clearing out my tube collection. I do not have a tube tester but I have only purchased from reliable sellers and all of my tubes are strong to NOS. I've only used these tubes several times. Will ship in a tube box and will be carefully packaged. Sold as is. Reasonable offers accepted.
Check out my other listings for records, tubes, headphones, and other headphone amps. I will be listing more over the next several weeks. Doing some fall cleaning!
