I have a GRAY GLASS military 6SN7 -GT VT-231 JAN - CKR - 6SN7> tube for sale. This is my favorite 6SN7 tube. I had used this tube on and of in my Conrad Johnson tube amp. However, one of the two tubes became very microphonic in my amp. So I am selling the good one and add the microphonic one as a 'gift'. It may wok fine in your application.
I've tested both tubes in my tube tester and it checked 80/80. For comparison, all my other NOS 6SN7 tubes test 80 in the same tester.
The base is tight, no gases or shorts inside the tube.
Will sell for SOLD shipped in the USA
Again the microphonic tube comes for free with this tube.
