Matched Pair General Electric GE 6SJ7 6J8P Vacuum Tubes NOS-Testing Type Mesh Plate there are a few scratchesThis new old stock testing, perfectly matched pair of GE 6SJ7s was tested on our Paul Hart calibrated TV7 U for shorts, gas and transconductance. There were no shorts or gas. Transconductance measured 57 for both tubes where minimum (65%) is 40. They have 3 13 188 5 and 3 26 188 5 date provenance codes, respectively. I am playing them as I write in my Musical Paradise MP 301 MK3 and they sound excellent. WE HAVE SCORES OF THOUSANDS OF VACUUM TUBES. IF
