Super Silvertone 6J7 6J7G Vacuum Tube Mesh Plate Shoulder ST-Style With Shields gas and transconductance with 400

gas and transconductance with 400 volts on the plates and a bias of -48 volts

dimpled-sheet getters and terrific flashing

5 volts with adapters (not included) and they sound tremendous even though they are running with a lowered filament voltage

This new old stock-testing matched pair of Ken-Rad 6V6GT output tubes was tested on our Maxi-Matcher 2 with 400 volts on the plates and a bias of -36 volts for shorts

but I do not recommend using them at any other filament voltage than 12

Super Silvertone 6J7 6J7G Vacuum Tube Mesh Plate Shoulder ST-Style With Shields gas and transconductance with 400This 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
