(1) RCA JAN CRC 6SN7-GT VT-231 Smoked Bottle. 

TThis listing is for a single RCA JAN CRC 6SN7-GT VT-231 Smoked Bottle tube. 

The tube tests at: 

Tube 1 (T1/T2) 3,500/3,900 umhos. The minimum for this tube is 1640 micromhos (GM). N.O.S. for this tube is 2,600 umhos.

So this tube tests like new. My tubes are tested on my calibrated Hickok 539B tube tester. I do not test for noise unless I can plug the tubes into an amplifier. The tube tester/AM radio noise test is not reliable.

Please Note:

If you have any questions, please ask before bidding/buying. This is vintage electronics component and it currently works very well. It is being sold AS-IS with no returns unless the functions I describe do not work when it arrives. 

All tube testers vary somewhat with their readings for the same tube, even one's that are the same model. If your tube tester gives you a different reading than what I got, that is not a reason for return. A difference in values between testers under 5% is considered normal.

I don't offer a tube rolling service so you should know what a 6SN7 tube sounds like in your amplifier because I'm not taking returns because a buyer doesn't like the sound.   

Thank you.
