Super Silvertone 6J7 6J7G Vacuum Tube Mesh Plate Shoulder ST-Style With Shields gray plates and excellent flashingThis 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.
