Super Silvertone 6J7 6J7G Vacuum Tube Mesh Plate Shoulder ST-Style With Shields but I do not recommendThis Super Silvertone 6J7G tube was tested on our Paul Hart calibrated TV7 U for shorts, gas and transconductance. There were no shorts or gas. It measured 40 where minimum (65%) is 31. I have played it in my Musical Paradise 301 MK 3 with an adapter (not included) as a 6SJ7 substitute and it sounds excellent airy with excellent dynamics and signal bandwidth. WE HAVE SCORES OF THOUSANDS OF VACUUM TUBES. IF IT'S NOT LISTED, WE MAY HAVE IT. PLEASE ALSO
